TwistedWave is a very easy to use and powerful audio editor. It supports Audio Unit plug-ins and many file formats, including wav, aiff, caf, mp3, mp4, FLAC, Ogg/Vorbis and ambisonic sound files. Good multichannel support. TwistedWave lets you easily add, remove or reorder channels. You can also apply Audio Units to multichannel files, or to a selection of channels. Unlimited undo and redo which works instantly. Zooming in and out of the waveform is very fast. Option-click and drag the mouse to zoom very accurately, while the waveform is being refreshed more than 100 times per second, even when the files are several hours long, or when the file has not finished loading, or when an effect is being applied. When TwistedWave is busy loading a large file, or applying a complex effect, all the work happens in the background, and you can continue working with your document, applying new effects. With TwistedWave, you never have to wait for the end of a long computation.
Working at a resolution up to 24-bit and 192 kHz sampling rate, TwistedWave enables you to work at a professional quality.
Besides using all of my plugins, it's fast redraw means more productivity for me. I started audio editing with digidesigns audiomedia II and have missed using playlists. TW has included that feature and I use it to edit interviews.
No complaints though I would like a TW app for my iphone.
I have been an early adopter and fan of Twisted Wave. I regularly export audio from FCP into TW and like its simplicity and interface. The metering is large and useful and the waveform display is also nice. Regular upgrades are always enhancing the product and as a multimedia producer it is my first choice for an audio editor.
Twisted Wave can layer effects and helped me clean up some problematic sound I had in a video project. Other programs provide similar functions but none have ever worked so well as this one for me... impressive.
