The Audio Manager allows you to tweak the maximum volume of all sounds playing in the scene. To see it choose Edit->Project Settings->Audio.

Properties

Property: Function:
Volume The volume of all sounds playing.
Rolloff Scale Sets the global attenuation rolloff factor for Logarithmic rolloff based sources (see Audio Source). 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).
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
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 clips, but AudioSource. Play calls and playOnAwake will not be handled in order to simulate behavior of the standalone build.

Details

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.
