VS1063 is the new flagship of VLSI Solution's MP3 slave processor family. As a first in VLSI's over decade long history of creating innovative audio IC products, VS1063 is as much aimed at encoding as it is at decoding audio.

The VS1063 IC can encode an unforeseen multitude of audio formats, from MP3 and Ogg Vorbis to G.711 u-law, G.711 A-law, G.722 and 16-bit PCM. The proprietary MP3 encoder and Ogg Vorbis encoder have been carefully tuned for highest possible audio fidelity for high-quality audio streaming or recording.

VS1063 can play back MP2, MP3, WMA, OGG, LC-AAC, HE-AAC, FLAC, IMA, G.711 u-law, G.711 a-law, G.722 and WAV PCM formats, making it very suitable for hi-fi audio playback and streaming applications.

VS1063 also offers a full-duplex codec mode with optional Acoustic Echo Cancellation. The codec mode makes is possible to create real-time full duplex audio for voice applications like internet phones and two-way audio radio links.

VS1063 provides many built-in sound effects, including a bass enhancer and treble control, a 5-band equalizer, 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 analog input on top of playback audio.

To make VS1063 even more versatile, it has 16 KiB of program RAM for custom applications. Combined with an interface with VLSI Solution's Integrated Development Environment VSIDE, the platform offers almost endless customization options.

Upgraders will be happy to know that from a hardware point of view VS1063 is a drop-in replacement for VS1053.

All these features, combined with CD-quality Analog-to-Digital and Digital-to-Analog signal path performance, make VS1063 an easy-to-use audio codec IC that offers versatility unlike any audio codec IC before it.
