You can specify that all new audio names recorded using state table actions are compressed, or that they are all not compressed. You specify this by using a Blueworx Voice Response system parameter named Audio Name CompressionType (see Audio Name CompressionType). You can do the same for user greetings by using the new User Greeting Compression Type system parameter (see User Greeting Compression Type).
When an audio name or user greeting is compressed, it occupies approximately 5 times less disk space than it would if it were uncompressed. On playback, some of the original audio signal is lost, and in some installations, users might notice a reduction in quality. This can occur if the voice data is recorded in a noisy environment.
An audio name or user greeting that is uncompressed uses all the original signal when it is played back, so no reduction in quality occurs. However, uncompressed voice data requires more disk space to store it, and more memory to process it than compressed data does.
