Mixere is a free, open-source application for mixing audio files. It runs on Windows NT/2000/XP, and supports WAV, AIFF, MP3, Ogg Vorbis, Flac, and Mod audio files. Mixere is ideal for live performance, and especially for creating multi-layered sound collages. It`s like a rack full of CD players connected to an automated mixer. Features include: dynamic looping and triggering of audio - automated volume, pan, and pitch sliders - soft (gradual) mute/solo operations - crossfading between documents - snapshots, for rapid scene changes - unlimited undo - clipboard support, drag and drop - variable automation waveforms - intuitive and easy to learn - comprehensive help - low CPU/memory usage - unlimited audio file size - no installer, standalone .EXE file. A Mixere document consists of a number of tracks, each containing a single audio file. Any number of tracks can play simultaneously, subject only to Windows and sound card performance limits. Audio is streamed directly from disk, so there`s no limit on audio file size, and no waiting for audio to be loaded into memory. Mixere`s interface is similar to a spreadsheet. The rows are tracks, and the columns are properties which can be adjusted for each track: name, transport (play/pause/stop/loop), mute/solo, volume, pan, pitch (two octaves), and audio position. Mixere doesn`t record, but its output can be captured using a third-party audio capture tool, such as River Past Audio Capture (highly recommended!). Mixere doesn`t use much CPU or memory, so it coexists peacefully with other audio applications. Mixere is licensed under the GPL, and uses an open-source audio library called Audiere. It`s a standalone executable, so there`s no installer. Try it! If you don`t like it, just delete it.
