  Audio mixing - Wikipedia, the free encyclopedia
Audio mixing is used in sound recording, audio editing and sound systems to balance the relative volume and frequency content of a number of sound sources.
At other times, audio mixing is done in studios as part of multitrack recording in order to produce digital or analog audio recordings, or as part of a film or television program.
An audio mixing console, or mixing desk, has numerous rotating controls (potentiometers) and sliding switches (faders) that are used to manipulate the volume, the addition of effects such as reverb, and frequency content (equalization) of audio signals.

 Mixing console - Wikipedia, the free encyclopedia
In professional audio, a mixing console, mixing desk (Brit.), or audio mixer is an electronic device for combining (also called "mixing"), routing, and changing the level, tone, and/or dynamics of audio signals.
Mixing consoles are used in many applications, including recording studios, public address systems, sound reinforcement systems, broadcasting, television, and film post-production.
As audio is heard in a logarithmic fashion (both amplitude and frequency), mixing console controls and displays are almost always in decibels, a logarithmic measurement system.

Audio mixing on a personal computer (A machine for performing calculations automatically) is also gaining momentum.

 Gamasutra - Mixing and Surround Sound - Digital Audio Mixing
Having the addition overflow while mixing is a real problem because when values go out of range, the amplifier and speakers have no way of knowing, so they try to reproduce the waveform that the data stream represents.
Mixing two or more digital audio tracks is the easy part of the mixing library; Simply add the samples from each track together.
Since these functions mix stereo input channels together before mixing with the output buffer, and I wanted to allow playback of cutscenes with stereo soundtracks, I added two mixing functions for 8 or 16-bit stereo inputs that do not mix the two source channels together before they mix them with the output.

 Audio Mixing Tutorial
Audio production is a critical process that makes your music realistic and pleasing to the ears.
In the days before computer recording and mixing, a reverb or equalizer was a piece of equipment in a rack, now it is software that is loaded into the computer, and the computer is responsible for processing these plugin devices.
Since audio travels in a specific direction, it is important to understand the routing of the signal chain or signal flow as some call it.

In real life, when you hear audio from two sources simultaneously, what you hear is the sum of the signals.
When I tested this mixing method, I got the expected result: as I mixed multiple audio streams I heard the contributing signals clearly, without distortion or loss of volume.
For instance, mixing two silent signals with a value of 128, I get a result of 192, which is not the sound of silence.

Audio mixers, including the audio mixer on the Videonics Sound Effects Mixer and Video Equalizer, can be used to add sounds to a videotape.
Simply put, audio mixing is the combining of music, sound effects, and narration (voice-over) with the sound on the original tape (called the native sound).
The advantage of this method is that the final tape will have the correct mix on all its sound tracks and can therefore be heard correctly regardless of the sound features of the player.

You generally have a little less than the amount of audio that you have buffered to perform the mixing.
In general, you will get better performance, if you have low overhead in the mixing, by doing the decoding in the callback, but if the processing overhead is too high, you will hear skips in the audio.

 Audio Mixing Console - Part 2
There are two main types of mixing module - a stereo unit to accept the outputs of the Mic/Line modules, and a mono version for the Auxiliary sends that includes an Aux return as well (these are typically used for effects, or as a simple foldback mix).
As shown, channels 1 and 2 are switched to Mix Bus 1, channel 3 to bus 2, channels 4 and 5 to bus 4, and channel "n" to the master bus.
The virtual earth mixing buses are particularly succeptible to magnetic flux leakage from transformers, and a separate supply will eliminate this problem, and helps to keep the weight down as well.

 NetBSD: Ideas on Audio Framework
Tamura Kent formally unveils his plans to add new functionality to NetBSD's audio framework (audio(9) [1] and audio(4) [2]) - specifically, the addition of an audio converter pipeline and in-kernel mixing.
These additions along with audio device cloning would make it possible to natively support hardware mixing without the use of a software based soundserver.
However, Kent's initial plans are to support software mixing first, with hardware supported mixing being considered a "nice-to-have".

Audio mixing should indeed be done at the ALSA level IMO.
From my understanding of dmix from when I implented it, programs access it (which it is basically the alsa drivers) and it mixes the sounds and sends them the /dev/dsp, which is why if you start a program that uses oss you can't play any other sounds b/c it access /dev/dsp directly.
If it does support hardware mixing, then the whole thing is fairly seamless as far as the user sees it.
