Mixer4 is a high precision audio mixer and processor. You can use either simple text files or an optional GUI to control volume and effect settings.

Features:

• Data (such as volume and pan settings) is accessed by the user in plain text files.
• Can be run without a desktop, a windows manager, or a soundcard.
• It is virtually unbreakable by other code/dependencies since it uses only the Alsa library (on Linux) and built-in C libraries.
• Integer math summing for precision.
• Direct signal paths and minimal processing whenever possible.
• Built in 64-bit precision equalizer, compressors, and reverb.
• Fast offline rendering with preview mode for hearing sections only.
• Panning works on principle of time delay or user settable pan law.
• Volume automation and ramps.
• 127 tracks and 8 stereo submixes.
• Works on 32-bit or 64-bit operating systems.
• Run simultaneous mixes or submixes on different cores.
• Installs simply by copying the very small binary to a working project or applications directory.
• User choosable audio file time placement (time stamping).
• Beat or time based automation entry with adjustable tempo and meters (tempo mapping).
• 8 submix groups
• 8 VCA style fader groups

Limitations:

Audio playback requires another program or utility.
Reads and writes 16 and 24-bit .wav files only.
No editing or recording capability (see Recorder7 on main page).
Does not integrate with other software plug-ins.
Automation is limited to track volumes.
Works offline only: workflow is adjust, render, then listen.

Latest Updates:

• Effects can be re-ordered on a per channel basis (in text mode)
• Parametric Plate updates and bugfixes
• high and low pass filters for reverb
• VCA style faders
• GUI supports VCA faders and reverb filters
