1. Simple description

SoundVQ is high-performance software for compression of audio data. The SoundVQ Encoder is used to compress the audio data. The SoundVQ Player is used to play the compressed data. SoundVQ uses TwinVQ (technology developed by NTT) to realize a high compression rate of 1/20 while hardly damaging the sound quality.
The main features of SoundVQ are as follows:

Features of SoundVQ

[Encoder]

• High compression ratio while minimizing any loss of sound quality
  High compression ratio while minimizing any loss of sound quality Audio data can be compressed to one tenth or twentieth of its original size. "TwinVQ" technology ensures that the sound quality of the compressed data remains virtually identical to that of the original data, allowing near-CD-quality data (16 bit 44.1 kHz stereo) to be distributed. For less critical applications such as human voice or sound effects, the transmission time can be shortened by limiting the frequency or raising the compression ratio. (22 kHz or 11 kHz, monaural, etc.)

• Audio data can be easily distributed without special hardware or servers
  The compression software runs on Windows 95/NT 4.0, and allows audio data (Windows WAVE format, Apple AIFF format) to be compressed on a Windows computer without special hardware. No special server is required for distribution, and any provider can distribute audio data just by making some simple settings on their existing server. SoundVQ can also be used on intranets.

• Easy use in home pages
  Compressed audio data can easily be embedded in home pages. Even individuals can create audio-enabled pages or pages with voice messages, for a revolutionary leap in expressive potential.
  
  

• Copyright protection and restricted distribution are supported
  "Stream Playback" which leaves no audio data on the receiving computer can be used when copyright protection is a concern, so that unauthorized duplication can be prevented. Of course it is also possible for the audio data to be left on the received device. Since the standard Internet access limitations are supported, distribution of music data can be limited to specific users.

[Player]

• Easy operation linked with your Internet browser
  The player functions as supplementary software (a helper application) for an Internet browser. Once settings have been made, you can browse web pages without being aware of the "Player" software, and the audio content provided by the author will playback automatically. Browsers supported are Netscape Navigator Version 2.0 or later, and Internet Explorer Version 3.0 and later.

• Stream playback allows playback during reception
  "Stream playback" allows you to listen to the sound while the audio data is being received, instead of having to wait until all data is received before beginning playback. This makes it possible for playback to begin immediately, even for large amounts of audio data.
