Alvas.Audio at a Glance
The Alvas.Audio package includes a PlayerEx component to let your application play sound in WAV format. Additionally, an application can play data from the file or memory stream, pause and resume playback, play mixed audio data and get the current sound position. Audio data can be played from any player installed in the system of an end-user.

Another component in the package is a RecorderEx. It enables an application to record uncompressed (PCM) and compressed (IMA ADPCM, Microsoft ADPCM, CCITT A-Law, CCITT u-Law, GSM 6.10, Windows Media Audio V2, MPEG Layer-3) audio in the WAV format. Audio data can be recorded to the file or memory stream. Recording can be paused or resumed, users can get the current sound position and record data to any recorder application installed on their system.

Among other components, developers will find AudioCompressionManager, which adds system-level support for transparent run-time audio compression/decompression (conversion) and waveform-audio data format selection.

There are also WaveWriter, a class for writing audio data to the stream, and Mixer, a component to control the routing of audio lines for playing or recording.
