Audio Encoding AAC Ogg gips

Recently, I found 2 New Audio Encoder (compression encoding) on the Internet ):

AAC (advaced audio codec), Advanced Audio Encoding, which provides better sound quality at a low bit stream than the popular MP3. It is charged.

 

Ogg, Official Website: www.xiph.org. You can get the corresponding documents andSource code-Libogg provides three operating systems: Windows, MacOS, and MacOSX. Free of charge.

 

Ogg is also a sound encoder for low bit streams.

 

However, there is no specific time to use its encoder for testing, so the compression ratio still has the same bit stream of audio to be further discussed.

 

Gips

Type: Audio

Developer: Swedish global IP sound company

Required bandwidth:

Features: gips can automatically adjust the encoding bit rate based on bandwidth conditions to provide high-quality audio at low bit rates. Core Technology of gips (Network AdaptiveAlgorithmPacket Loss Compensation Algorithm and echo elimination algorithm) can effectively solve the problem of voice latency and ECHO, bring the perfect sound quality, and provide a clearer voice call effect than the phone call.

Advantages: it can effectively solve the problem of voice latency and ECHO, bring perfect sound quality, and provide voice call effects clearer than the phone.

Disadvantage: not free

Application: VoIP

Royalty: an annual usage fee

Note: gips audio technology is an internet-specific voice compression engine system provided by "Global ipsound", the world's top voice processing technology company from Sweden. Gips can automatically adjust the encoding bit rate based on bandwidth conditions to provide high-quality audio at low bit rates. The core technology of gips (network adaptive algorithm, packet loss compensation algorithm, and echo elimination algorithm) can effectively solve the problem of voice latency and ECHO, and bring perfect sound quality, provides better voice calls than phone calls.
