How to select tracks/channels in Sound Studio 4.7.0 and later:

To select an individual track or set of tracks in Sound Studio, hold down the Command key and then click on the track(s) you'd like to select. By default, clicking once in the main waveform view automatically selects all tracks. Many users were previously unable to easily select and edit all tracks in Sound Studio, so we made this change to make this feature possible. You can read more about this feature in our user manual under Keyboard Shortcuts at


Release Notes:

Fixed a bug with markers in the CAF file format.

Review by Clark Baker

Not too complicated and does what I need - I have been a satisfied user for about 10 years and have many editing hours on versions 2 and 3. While I have only used this release for a short time, it retains the features and simplicity of use that I love. Here are just a few features I use: Drop markers while music is playing Zoom and adjust markers to exact beat boundaries so I can cut, copy, and paste seamlessly Select a region, perhaps between markers, and with “loop when playing” start playing near the end of the selection and hear how it sounds looping back to the beginning of the selection Adjust temp without changing pitch Paste mix – the ability to layer existing music onto new music. Sometimes in separate buffers I fade out one piece, fade in a separate piece, and paste mix the two together to get a transition When I need music in the left track and voice in the right track, I use mixdown to mono to create mono tracks of each, and cut and past the music into a new “L” track and the voice into a new “R” track. In the rare cases I have needed it I have received good support. Things it doesn’t do: Compute BPM, automatically place markers every beat (or 4 beats or 16 beats), beat align transitions between songs like a DJ might, automatically adjust the volume level so an entire podcast or talk or piece of music is at about the same volume, “cleanup” recordings made from an LP (pop, hiss, wow, flutter) but I understand there may be plugins for some of these functions.

Version 4.6.4
Review by Nutcracker13

I bought this program to edit MP3 files now they have removed that ability - I use this app to edit MP3 recordings of church services. Now they have removed the ability to save MP3 files and removed the reference to that ability from the description. Therefore my purchase is now worthless. Don't waste your money on an application that will arbitrarily remove major features after you purchased the app for those advertized features.

Version 4.8.12
Review by diego_enchilada

Excellent App - Been using Sound Studio for years, and I love it. I’ve used (and own) Logic, Audition, and Pro Tools, and when I need to do some quick edits to a file Sound Studio is my preferred app. It forgoes all of the bloat that come with the big apps and lets you get right to work. I’d recommend it to anyone doing audio editing.
