Alvas.Net announces the release of Alvas.Audio version 2016.0.

Alvas.Audio for .NET is 100% CLR compliant and written in pure C#.

Audio is an integral part of many software applications. Alvas.Audio from Alvas.NET enables developers to add audio capabilities to different .NET applications:
  • play, record and convert uncompressed or compressed audio data;
  • pause and resume playback or recording;
  • record and play data to or from the stream;
  • play mixed audio data;
  • set up mixer controls;
  • get the current sound position;
  • view the level of the input sound signal;
  • get the format list for specified WaveFormat;
  • get audio stream duration in milliseconds;
  • change Wave stream to MP3 stream if the former contains "MPEG Layer 3" data;
  • play, record and convert RAW headerless format (SLINEAR etc);
  • play and extract audio data from Avi streams;
  • encode and decode Dialogic .vox (adpcm) format data.
  • convert audio wave stream to mp3 stream
  • convert Dialogic .vox (adpcm) stream to Mp3 stream
  • insert and mix audio data into main audio data with specified offset multiple times
  • split stereo audio stream to two mono streams
  • merge 2 audio mono into one stereo
  • reverse audio wave stream
  • sign library with strong name. Audio library can be added to GAC

What's new in version 2016.0?

New classes and methods were added:
  1. AudioCompressionManager.Mp3ToMono method converts Mp3 Stereo into Mono.
  2. AudioCompressionManager.WaveToMono method converts Wave Stereo into Mono.

Alvas.Audio at a Glance

The Alvas.Audio package includes a PlayerEx component to let your application play sound in WAV or MP3 format. Additionally, library allows to play data from the file or memory stream, to pause and resume playback, to play mixed audio data and to get the current sound position.

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, MPEG Layer-3) audio in the WAV or MP3 format. Audio data can be recorded to the file or memory stream. Recording can be paused or resumed, get the current sound position.

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 Mixer, a component to control the routing of audio lines for playing or recording.
