Audio Commands from the Terminal

Some Audio tools available in the terminal

There are several UNIX commands that Apple provides to help with audio. These are executed from the terminal.

afplay

applay allows you to play audio files from the command line.

    Audio File Play
    Version: 2.0
    Copyright 2003-2013, Apple Inc. All Rights Reserved.
    Specify -h (-help) for command options

afinfo

afinfo allows you to get information on an audio file.

Sample output

File:           2004.mp3
File type ID:   MPG3
Num Tracks:     1
----
Data format:     2 ch,  44100 Hz, '.mp3' (0x00000000) 0 bits/channel, 0 bytes/packet, 1152 frames/packet, 0 bytes/frame
                no channel layout.
estimated duration: 53.916735 sec
audio bytes: 1294001
audio packets: 2064
bit rate: 191999 bits per second
packet size upper bound: 1052
maximum packet size: 627
audio data file offset: 1027
optimized
audio 2375680 valid frames + 576 priming + 1472 remainder = 2377728

For me the most useful information is the Data format. In the above example, the 44100 Hz is a common sampling frequency - so the audio should play fine on most devices.

afconvert

afconvert converts file from one format to another.

Supported formats:

3GP Audio, 3GPP-2 Audio , AAC ADTS, AC3, AIFC, AIFF, amrf, m4af, m4bf, caff, ec-3, MPG1, MPG2, MPG3, mp4f, NeXT, Sd2f, WAVE

Interesting formats that is missing: oog (Common for streaming audio)

Sample output

# Converts MP3 to WAVE
afconvert -f WAVE -d LEI32 2004.mp3 -o 2004.wav
# FLAC
afconvert -f flac -d flac 2004.mp3 -o 2004.flac

afclip

afclip checks to see if your audio file has clipped sound - which is audio that is too loud and caused a clip.

Sample output

afclip 2004.mp3
afclip : "2004.mp3"    2 ch,  44100 Hz, '.mp3' (0x00000000) 0 bits/channel, 0 bytes/packet, 1152 frames/packet, 0 bytes/frame
 -- no samples clipped --

afhash

afhash is an audio file hash

The purpose of the hashing at offsets close to the start and the end of the file is to ensure that if a TAG editing tool modifies either the beginning of the end of the file, at least one of the two hashes should survive and allow us to get meta-data on a specific file.

Sample output

afhash 2004.flac
2004.flac :
MD5 Hash in file       : 41004751cb6cb5219a51e6935ec97b66
MD5 Hash of audio data : 41004751cb6cb5219a51e6935ec97b66
Hashes match.

Fix UnicodeEncodeError with BBEdit

Quick Easy Fix

Have you ever gotten this error when running your Python code:

UnicodeEncodeError: 'ascii' codec can't encode character 'u2019' in position 16520: ordinal not in range(128)
      args = ('ascii', '<!DOCTYPE html>n<html lang="en">n <head>n <m...rigin="anonymous"></script>nnn </body>n</html>nn', 16520, 16521, 'ordinal not in range(128)')
      encoding = 'ascii'
      end = 16521
      object = '<!DOCTYPE html>n<html lang="en">n <head>n <m...rigin="anonymous"></script>nnn </body>n</html>nn'
      reason = 'ordinal not in range(128)'
      start = 16520
      with_traceback = <built-in method with_traceback of UnicodeEncodeError object>
      

This has been happening to me a lot when I convert code from PHP to Python. It was frustrating to fix the error. Someplace in my code is a piece of text that isn't translating well.

BBEdit to the Rescue!

The easy quick fix I found is in the Text Status Bar in BBEdit. The text status bar shows the file encoding,

Change the Python File Encoding!

By default the coding is Unicode (UTF-8)

However, if you change the file encoding to Western (ISO Latin 1) something magical happens when you save.

Unmappable character(s) detected.

If there's any Unicode in your file, it warns you and then tells you where the Unicode is so that you can fix it!

Once you fix all the errors the file will save and the UnicodeEncodeError should go away!

Sample Unmappable Characters dialog box that shows you what you need to fix!

Alternative Fix

If you get ordinal not in range(256) - Check out my solution.

If the error is results from a Database data, check out out this solution.

Emmet in BBEdit

Code HTML faster in BBEdit

Emmet is an easy way for Web Developers to generate code from a series of shortcuts. It's a good tool for raw HTML and CSS developers.

Emmit support was include in BBEdit v.14 which was released in the summer of 2021.

Sample Emmet Command

Using Emmit expands to:

<div>
	<ul>
		<li><# $1 #></li>
		<li><# $2 #></li>
	</ul>
</div>

Setting up Emmet in BBEdit

To use Emmet in BBEdit you need to install it. You use Node Package Manager (NPM) to install the files. ( Emmet NPM page)

Got NPM?

If you haven't installed NPM before, or don't know if you have it installed - you can always download the node installer from Nodejs.org

Download the NodeJS installer from Nodejs.org website: https://nodejs.org/

After doing the NPS install, you will need to run the NPM install command to install Emmet:

Why not run the install command in BBEdit's Shell Worksheet?

Using Emmet in BBEdit

The important thing about using Emmet in BBEdit is that you use the "Expand Emmet Abbreviation" on the same line that you have type the abbreviation.

You do not select the text and then use the "Expand Emmet Abbreviation" command.

Copy the following into any BBEdit window:

At the end of the line use the keyboard shortcut Shift F5 or select "Expand Emmet Abbreviation" from the Edit menu.

If your into Bootstrap, this is a good one to know:

Output:

<card class="mt-3">
	<div class="card-header">
		<div class="card-body"><# $1 #></div>
	</div>
</card>

That created the basic card area in the Bootstrap universe.

Image Tricks Pro

Practical Image Utility

Belight Software makes a lot of great Macintosh software - Image Tricks is a cool image utility.

Image Tricks is a quick image application. You would use this software to make a quick adjustment to an image for social media or blog posts.

Features of Image Tricks

Core Image Filters - Access to all the built-in Core Image Filter filters in the Core Image API. Adjustments like Transform, Color, Focus, Distortion, Style, Halftone, Tile, Lumine, and Overlap. Apple has 174 of them. Image Trick Lite users get 118, whereas Pro users get 160. (Not sure which Core Image Filers are not in Image Trick)

Quartz Compositions - Users get access to Stylize, Distortion, Utility, Other. Use this set of filters to create comic book-like effects on your images. Image Trick Lite users get 35, whereas Pro users get 41.

Image Generators - If you don't have a background image, why not use Image Tricks and create one. Image Trick Lite users get 13, whereas Pro users get 20. The nice thing is that after you generate a design, you can use the Quartz and Core Image Filters to touch it up.

Photo Frames - Quickly add a frame to your image. Some of these are not scaleable so your image may crop. Image Trick Lite users only get 12, whereas Pro users get 115.

Border Masks - Don't settle for boring square corners on your photos, add a border mask for an interesting effect. If you know how to create masks in Affinity Photo or Photoshop, this may not be an exciting feature. The advantage of Image Tricks is that they are super easy to apply and switch to see which design works best. Image Trick Lite users only get 35, whereas Pro users get 149.

Masks - These add image overlays to your image. Image Trick Lite users get 36, where as Pro users get 76.

Image Tricks Pro

You can buy Image Tricks Pro for $9.99 in the Apple Store or from their website.

One More Thing

Belight Software is based in Ukraine. As of today, all their developers are still in Ukraine. You can help support Ukraine Developers by purchasing their software. Following BeLight Software on Twitter for all the updates from the front lines.

I have been thinking of purchasing Image Tricks for years - I finally decided to purchase it to help support the Macintosh Developers in Ukraine. It's not an application that I plan to use a lot, but it seems the right time to buy.

Path Finder 2021

Latest Update to the popular Finder replacement

PathFinder 10 was released earlier this month. The last update was on December 8, 2020. This means that there was a 1 year, 2 months, 5 days duration between major releases.

What is Path Finder?

Path Finder is a more advanced Finder. The application makes available a lot more tools to help increase your productivity.

People use Path Finder to:

• Perform Advance Search - Look for files in particular locations - such as certain USB drives.
• Manage Files - Easily move files from one location to another.
• Navigate - Using the Application Dock or the Menu icon, you can easily open up locations no matter where you are on your computer.
• Productivity - Power up the your finder with a lot of extra tools.

Let's check out the new features and see if it's worth the upgrade.

CocoaTech is no longer adding the version to the PathFinder name. They are planning on releasing monthly updates and they felt having a version number in the name may confuse things.

Cocoatech has also moved Path Finder to a subscription model. This means that you now have to pay annual fees to get the latest version. They dropped the price, a yearly plan now costs $29.95. Path Finder 10 was $36.

Cloud Folder Uploader - You can easily send a file to any cloud service simply by right-clicking and uploading a file to SFTP/FTP, Amazon S3, Dropbox, and Google Drive servers.

Bug Fixes -Fixed issues with Terminal, git, and SVN modules

sFTP Cloud Uploader

The sftp integration is cool, it just takes a bit to get used to set up. Some tips I learned:

• The Remote Path is from the root directory when you log in to the sftp server. This isn't the absolute path, just the path you would take logging in.
• Make sure to end the Remote Path with a directory slash, example: images/website/
• Cocoatech should add a "Test Connection" button which would make it easier to see if you type the right password or file path.

You still can't mount an sftp server to Path Finder - maybe in a future release? Sending files to sFTP servers is a great first step.

Some Bugs with Monterey

There are still some issues with macOS Monterey. I am not seeing detailed information when I get file information. It seems to be working for macOS Catalina. (Apparently, this was supposed to be fixed in the 2121 version.)

I am also having some issues with the "Symbol Table" reports - works in Catalina but not in Monterey. This is pretty minor as a lot of people probable don't use this feature.

Revisiting Some Path Finder Features

Back in January 2021, I wrote about some of the new features of Path Finder 10, I thought it might be good to revisit a few of these features again.

File Rename - The file rename dialog allows you to have multiple criteria in renaming files. Really a good way to rename similar files. The before/after is really useful to see the impact of the changes before they are applied.

iPhone Viewer - Use the Size Browser to see where the largest files are being kept on your phone.

Application Switcher - See all the available applications on your computer. Not just the applications in the ~/Applications folder. This is available in the menu bar

Photoscape 4.2.1 Update

List of the Latest Features

It has been a while since I posted an update of all the features in PhotoScape X. This week's post is look at some of the features added since my .PhotosScape Update in November 2020.

Version 4.2 shipped in January 2022. This is the release note on the new features:

• New Object Effects: Inner Glow, Inner Shadow, Emboss
• New Image Effects: Outline
• Added Background, Fill, Color, Masks options to Image and Sticker Objects
• Added Mask option to Color and Film Effects
• Added Close menu to Collage tab
• Added 'Merge Selected Layers' to Editor tab
• Added 'Font Favorites'
• Added 'WEB Quality option'
• Added 32 Camouflage Patterns
• Added 180 Flower Stickers
• Added 469 more Pixel Stickers
• Selecting and Editing Multiple Objects
• Improved Object Effects: Long Shadow, Overlays & Masks
• Improved Shadows/Highlights Filter
• Improved Ul
• Fixed bugs

Quick Sample of some the the features in this update

Six Things I Learned from the New update

This update was a month late! In the past, PhotoScape did their major updates in Oct/Dec. I am not complaining, I just like to see what cool things that the PhotoScape team comes up with.

The Inner Glow, Inner Shadow are great ways to add make text objects stand out more.

Webp capability - Now I can save files in Webp format and see the savings using that format. (For example, the image used in this Blog post is 40 KB had I used Jpeg format it would have been 76 KB)

Note: Affinity Photo, Affinity Designer, and Graphic Converter don't offer support for Webp. Pixelmator Pro does allow users to save in Webp format but PhotoScape is the only app that I have that shows the preview of the saved image.

Font Favorites are a great addition! Now I can quickly switch between fonts and not have to scroll the long menu just to get to a font that I want.

The flower stickers and pixel stickers are nice, but I don't think that I'll ever use them. I guess its a good way to create a comic graphic? There's a lot of variety in the Pixel stickers, certainly worth a scroll through to get ideas.

The Camouflage Patterns are a nice addition to the large pattern library. They add a nice touch as a background color in text. I didn't realize that there were 32 different camouflage patterns.

Luminar Neo

Version One Released today

This week, Skylum finally shipped version 1 of Luminar Neo. In this release users get the Core Luminar features, Remove Dust Spots, Relight, Remove Powerlines, Luminar Share, Presets and Layers.

In a later release the Mask and Portrait Background removal will be available - there is no date on when that release will occur. It will be a free update.

Product Description

Before/After

Check out how Luminar Neo transformed a boring church photo into something awesome:

Previous Next

This photo was taken using the GoPro Hero 9.

Key Features of Luminar Neo

Features not available in other Luminar products

Luminar Neo's goal is to make a single image look awesome. Luminar AI is designed more for batch editing, like Lightroom

Specific features not found in Luminar AI: Relight, Develop and Crop.

Relight is the ability to change the lighting in a photo. You can add or darken an image with a simple click. The cool thing is that Neo produces a 3D map so the light spreads naturally in the photo.

Develop is you opportunity to change the Exposure, Smart Contrast, Highlights, and shadows.

Crop is very similar to the Composition tool in Luminar AI. Clicking on Crop gives you the best crop image - making sure that the portrait's eyes are in the center of the image. Luminar AI adds Persecution and Image 3D Transform.

Argumented Sky Removal. It's interesting to note that Luminar decided to remove Argumented Sky in Luminar Neo. Argumented Sky is where you can place objects in the photo such as the moon or a rainbow. I recall seeing it in early versions but that feature is now gone.

You can get advice and tips from the Luminar Insider Form. The form is an active place of die-hard photo users. They frequently run contests for the best photos or styles.

Luminar Neo has Presets just like Luminar AI. When I ran the same image, the preset suggestions were the same. However, I rarely use these and would rather spend a few minutes in the editor fine-tuning the image using the awesome tools.

ForkLift 3

Is it a better alternative to Panic Transmit?

ForkLift by BinaryNights is a very popular dual file manager. In 2012, I did a quick review of the application and things have changed a lot over the years, so I thought it would be good to review it again.

My go-to FTP file manager is Panic Transmit, so this review is based on the things that ForkLift does well and some things where Transmit does a better job.

Five Things I Like about ForkLift 3

Commands - The Command menu option allows you to send various server commands without having to open up a separate terminal window. You can make symlinks, alias, sync, compress, copy, and delete to name a few.

Local File Size - You can quickly tell how much space you have on your local devices, if you are run low on disk space, the ???pill??? color will be red.

Sidebar - You can have the sidebar visible whenever you need it. This makes it easy to navigate between favorites and local devices while still having a two-panel window visible. This would be useful when migrating a site from one cloud service to another.

Custom Shortcuts - You can set or change any Forklift preferences. This means that I can quickly navigate through the application using shortcuts that I am familiar with.

Forklift Mini - This puts some features of ForkLift in the menu bar. For each favorite, you can mount it as a disk, open it as a droplet or open the location in Forklift. To mount it as a disk you need to install ???FUSE for macOS??? a free third-party framework,

Two Things That Panic Transmit Did Better

Apple iCloud Drive - When viewing iCloud folders, Forklift doesn???t show files that haven???t been downloaded. Panic Transmit does show non-downloaded files.

Connecting Servers - I spent way too much time looking at how to connect a server. In Transmit, the connection location is easy to find and the interface is much better.

Recommendation?

Overall, I think Transmit is a great application and won't be switching to ForkLift anytime soon. However, if I fund that ForkLift is running a sale, I may consider purchasing as a secondary FTP tool.

Smart Folders
