Best Free Audio Editing Software

Best Free Audio Editing Software

Thanks to subscriber Jay Eitelman for this suggestion: "Gizmo, I've switched from using $349 Adobe Audition to using Audacity [1]. It does all the recording and editing I need, and is much simpler/faster to use. Check out the noise reduction - it even allows you to select a noise profile - then remove the profile - just like Audition. " Thanks Jay. I note that, according to the web site, Audacity will also "record live audio, convert tapes and records into digital recordings or CDs, edit Ogg Vorbis, MP3, and WAV sound files, cut, copy, splice, and mix sounds together and change the speed or pitch of a recording."

Subscriber Brandon Tanner however differs: "Audacity is good but you should check out Kristal; I think it might have Audacity's number! To start with, Kristal has an ASIO driver while Audacity doesn't. That means that you can monitor your pre-recorded tracks in real-time while you're overdubbing new ones, mandatory when multi-track recording. You can't do that in Audacity as the latency is too high. Second, Kristal supports VST plug-ins. There are tons of quality VST effects and instruments floating around the net, a lot of them free. Audacity's effects are not quite up to par with some of the better VST ones. Not to bash Audacity but I have to give credit where credit's due. Third, Kristal has a 'proper' multi-track mixer, with a lot more options for routing individual tracks, effects, etc. Don't get me wrong, I like Audacity and I think it's a good program as long as your needs are basic. But Kristal definitely has more 'pro' features."

Rinchen Tsepal takes a different view: "Audacity can support VST plugins but this support is not "built-in" because the code is not 100% open source and must be kept separate for licensing reasons. The "VST Enabler" is available for download from the Audacity website, and is available for Windows, Mac OS-X and for Linux (as a LADSPA bridge apparently). They do claim that support is limited for the time being - but also that full support is coming. Additionally real-time monitoring can be enabled through preferences - although it's not selected by default."

Kristal is based on a 32-bit floating point audio engine that can handle sample rates of 44 to 192 kHz with word sizes of 16, 24 or 32 bit. It comes with a three band parametric EQ and supports WAVE, AIFF, FLAC, OGG Vorbis file formats. It can only handle a maximum of 16 audio tracks, though the web site mentions an upcoming version 2 that will handle more tracks as well as support for MIDI, virtual instruments, and a wider range of VST plugins. Like all media editing programs, Kristal requires a modern fast PC. Don't even think about using it with a sub 1Ghz machine.
