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.

13 lucky years with Sound Studio — Just great!

I am a professsional radio broadcaster and often need to edit interviews, music, speech, create mixes, features, and the like. I have been using Sound Studio since 2005 on a weekly basis (if not more) and have found it to be easy to use, full of pro features, and reliable. In fact, I don’t know what I would do without it.

Tried others - some too complicated for my needs, others so automatic-driven I have no control, still others crash during my work session losing all changes - and precious time.

Sound Studio is an amazing audio tool, priced right, and full of features that let you control what you want. I highly recommend it without hesitation.

My Go-To Stereo Editing tool

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.

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.

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.

Thanks for the review! We've got your feature request on our list and will consider it for a future update.
