1 min read
Audio specialist VLSI Solution has unveiled what it claims to be the world's most advanced audio codec chip, designed for a range of consumer and industrial applications.
According to the company, the VS1063 IC can encode a multitude of audio formats, from mp3 and Ogg Vorbis to G.711 u-law, G.711 A-law, G.722 and 16bit PCM. The proprietary mp3 and Ogg Vorbis encoders have been tuned for highest possible audio fidelity for high quality audio streaming or recording.
The customisable device is designed to play back mp2, mp3, wma, OGG, LC-AAC, HC-AAC, FLAC, IMA, G.711 u-law, G.711 a-law, G.722 and wav PCM formats, making it suitable for hi-fi audio playback and streaming applications. In addition, it offers a full duplex codec mode with optional Acoustic Echo Cancellation. The codec mode makes it possible to create real time full duplex audio for voice applications such as internet phones and two way audio radio links.
Featuring 16KiB of programme ram for custom applications, the VS1063 provides a range of built in sound effects, including a bass enhancer and treble control, a five band equaliser, a speed shifter and VLSI Solution's proprietary EarSpeaker room processing. It is also possible to insert PCM sound effects or audio from a stereo analogue input on top of playback audio.
