AudioImporter.compressionBitrate  

var compressionBitrate : int

Description

Compression bitrate.

This value is in bits/second, e.g. 128000 would be 128 kbps.

    // Prints the bitrate of the imported audio files

    class BitrateLogger extends AssetPostprocessor {
        function OnPreprocessAudio () {
            var audioImporter : AudioImporter = assetImporter;
            Debug.Log(assetPath + " - " + audioImporter.compressionBitrate + " bits/second");
        }
    }
