MediaLooks Audio Mixer is a DirectShow filter for real-time mixing of multiple audio streams.
Overview
The Audio Mixer DirectShow filter is designed for mixing an arbitrary number of PCM streams in various combinations.
For video mixing features please see our Video Mixer DirectShow Filter.
Audio Mixer is also available with the Audio Filter Pack.
Features
- Real-time mixing.
- Unlimited number of stereo or mono input & output pins.
- Unlimited mixing flexibility: any input pin can be mixed to any output pin.
Input/output format: PCM Audio.
Future features
- Mixing of several input streams into one multichannel stream (WAVE-EX).
- Automatic correction of input parameters to eliminate volume overflow.

GraphEdit usage instructions
Render two (or more) media files in GraphEdit. Connect uncompressed outputs to the inputs of the Audio Mixer and render one or more output pins (AM Out) of the Audio Mixer.
Open the property page of the Audio Mixer. The selector on the left shows the rendered output pins - if you have rendered only one one output pin, only "AM Out 01" is displayed.
The grid matrix on the right defines what is to be output to the selected output pin. Values from 0 (silence - in) to 1 (original level) are accepted. In the current version an empty field will also be treated as silence. If values higher than 1 are specified, the filter will work as an amplifier.
For editing the grid - either double click or press "Space" or "F2".
For example, if you have two input stereo streams and you wish to mix these streams in such a way that both of the input left channels are mixed to the right output channel and both input right channels - to the left, and at the same time decrease the volume of each channel by 30% - this is how your grid should look like.
