Audio Manager

The Audio Manager allows you to tweak the maximum volume of all sounds playing in the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

Property: Function:
Volume The volume of all sounds playing.
Rolloff Scale Sets the global attenuation rolloff factor for Logarithmic rolloff based sources (see Audio SourceA component which plays back an Audio Clip in the scene to an audio listener or through an audio mixer. More info
See in Glossary
). The higher the value the faster the volume will attenuate, conversely the lower the value, the slower it attenuate (value of 1 will simulate the “real world”).
Doppler Factor How audible the Doppler effect is. When it is zero it is turned off. 1 means it should be quite audible for fast moving objects.
Default Speaker Mode Defines which speaker mode should be the default for your project. Default is 2 for stereo speaker setups (see AudioSpeakerMode in the scripting API reference for a list of modes).
Sample Rate Output sample rate. If set to 0, the sample rate of the system will be used. Also note that this only serves as a reference as only certain platforms allow changing this, such as iOSApple’s mobile operating system. More info

or Android.
DSP Buffer Size The size of the DSP buffer can be set to optimise for latency or performance
Default Default buffer size
Best Latency Trades off performance in favour of latency
Good Latency Balance between latency and performance
Best Performance Trades off latency in favour of performance
Virtual Voice Count Number of virtual voices that the audio system manages. This value should always be larger than the number of voices played by the game. If not, warnings will be shown in the console.
Real Voice Count Number of real voices that can be played at the same time. Every frame the loudest voices will be picked.
Disable Audio Deactivates the audio system in standalone builds. Note that this also affects the audio of MovieTextures. In the editor the audio system is still on and will support previewing audio clipsA container for audio data in Unity. Unity supports mono, stereo and multichannel audio assets (up to eight channels). Unity can import .aif, .wav, .mp3, and .ogg audio file format, and .xm, .mod, .it, and .s3m tracker module formats.

If you want to use Doppler Effect set Doppler Factor to 1. Then tweak both Speed of Sound and Doppler Factor until you are satisfied. Speaker mode can be changed runtime from your application through scripting. See Audio Settings.
