Audio Mixer Pipeline

From SpacialAudio

Jump to: navigation, search

The Audio Mixer Pipeline section allows control over the Equalizer (EQ), AGC, DSP and Output for each audio player (referred to as an audio channel) found in SAM Broadcaster and SAM Party DJ.

Control over each channel of audio allows for flexible audio processing. For example, a vocoder DSP plugin on the Voice FX player channel can make your voice sound like a robot. And, since it will only effect the Voice FX player, the other audio channels will sound normal. Additionally, the option to run compressor/limiters on Deck A & B players before crossfading happens. In that way, the DSP processing will not interfere with the crossfade effect.

Take a close look at the audio pipeline and take a moment to understand how all the audio channels are finally mixed into one audio channel which is then fed into the output.

Basic Configuration

It is very important that you configure the Audio mixer pipeline to your specific needs. The following section aims to provide you with some basic information to help you set up the audio mixer pipeline.

Click on the EQ button to bring up the Equalizer.

The Equalizer is used to adjust the volume level of different frequencies of the audio. This can be used to boost or reduce the volume levels of the bass, trebble and voice to have finer control over the final sound.

Clicking on the AGC button will bring up the advanced audio processors.

The DSP button will bring up an interface that allows you to easily configure and use Winamp DSP plugins.

Clicking on the Air out (or Cue out if visible) button will bring up the Output configuration dialog. This will allow you to select the correct audio output device, as well as adjust the latency of the audio.

In order to avoid skips and blips in the audio, the application must have a high priority so that the operating system gives it enough CPU time to fill all audio buffers in time. This is especially important if you have set the output to a very low latency and have a slow computer (1GHz or slower) We recommend setting the Process priority to a level of Above normal to High.
