Who needs Cool Edit or Adobe Audacity?

This is definitely a league apart from the more expensive Toast (with included Spin Doctor). It may not be as colorful as Roxio’s hyped product, but it permits precise and relatively easy editing of wave patterns. It’s not a complicated program for the audiophile who wishes to edit more than one track and to edit “sound on sound." But for editing a single broadcast, or podcast, or musical file, nothing could be more clear, precise and user-friendly. Moreover, the audio is professional quality (I use it for NPR broadcasts), and if you’re “into effects,” this program offers as many as Adobe Audacity and other expensive programs. One notable feature that’s been added to this edition: Automatic and Timer Recording. In fact, the timer setting could not be more easy to set and convenient to review. Sound Studio is definitely not resting on its laurels. And yet the company has lowered its price for an unbeatable value.

Lately, or after Apple’s most recent update (possibly no relation to problem), I can’t seem to make Sound Studio see the songs from iTunes that I want to burn (in addition to my spoken commentary from a Blue microphone). Possibly an Apple program (or errant app) is prioritizing and nullifying my needs. I don’t recall doing anything more than sliding my iTunes on to the Sound Studio app, without redirecting them to my mic—I certainly wouldn’t want to re-record commercially recorded music on a microphone.

Thanks for the review! As for the iTunes songs, if you have downloaded the songs, you should be able to show the file in Finder from iTunes, and then open the file in Sound Studio.

My Go-To Stereo Editing tool

If you do any sound work you need this app.

I love this app. Clean UI, does all the stuff I need. It may not do FLAC or auto-split files as one reviewer complained about, but it’s not designed for that. You use this when you want do do some basic sound editing quickly; and when you don’t want to open up RX or PT or such to do your quick edit.

If you need to edit mono, stereo (I never use it for more than Stereo although I think it will do more tracks).. this is the bomb. I also use iZotope RX6 but that’s usually so much overkill. This app is much faster for opening and editing files. I can usually open up something in this and make the edit and re-save it faster than it takes RX to just open!!!

Amadeus may have “more features” but I hate the UI of it and I never use those features.

If you do any kind of professional level sound work, this is more than worth the $30.

My only “complaint" is a feature request: an option for storing sound device IO configurations when using this wtih multi-channel audio interfaces. Basically, I’d like to save Audio Input/Output settings and have a simple popup to switch to those settings. I’d also like a few things like shortcuts for saving your favorite or most frequently used Plugins.

An Absolutely Essential Tool

I love this app, I've been using it for well over a decade (back when Version 3 was out) and it's been an indispensable part of my editing life since.

Whenever I need to so quick little edits, compile master files, multitrack planning, just try something out, this is my go-to app. Sound Studio takes barely a second to load up, and is fairly compatible with most AU & VST plugins, which makes it great when I get a idea I wanna try out in the moment, and relegate setting up a file Logic for more complex projects.

It's a fantastic app, and if you're into audio, it's worth adding to your toolset; It's become as familiar to me as the mouse & keyboard I use to operate it, it might become the same for you. Thanks a bunch, Felt Tip Inc, for a wonderful editing app.
