It has the standard and advanced features for editing your digital audio files. Wavosaur can work with ASIO drivers for optimal performance, you can do audio routing, import wav, aiff, iff, mp3, AKAI S1000, vox, multichannel wav and raw binary files. General features: - accurate visualization, fast and easy zoom, easy to use and clean interface - play, record, pause, fast forward and rewind, real time resampling - cut, copy, paste, insert, replace, mix, trim/crop - normalize, fade in/out, mute, "vocal remover", reverse, insert silence, etc. - channel convert, resample, bit depth convert, auto-trim, silence remover - different available skins for the editor - export MP3 Advanced features: - Loop points and markers support : load, edit, save cue points for using with hardware/software samplers, automatic markers insertion (at BPM, on silence). - analysis tools : 2D & 3D spectrum, detailled statistics, sonogram. - Simple synthesis generators : generate waveform (sinus, triangle, saw, square, white noise, impulse train) - export multiple wav from marked region, export as text for import in software like Matlab, Excel, PSpice. Effects capabilities: Wavosaur has a virtual rack where you can add and chain VST plugins effects : you can use VST plugins in real time, displays the graphic user interface and tweak parameters in real time, this means unlimited possibility for sound designing, mastering, and all audio manipulations, thanks to the huge number of quality VST effects. Analysis features: Detailed statistics : RMS power, min & max value. Frequency analysis : 2D spectrum & 3D spectrum, sonogram. Real time oscilloscope & sonogram. Synthesis : waveform generator : sin, saw, square, triangle, white noise, frequency impulse train (useful for calibration and measurement). The batch processor lets you process many files at once. The soft can also be triggered by MIDI with a MIDI controler.
