8 SUPPORTED AUDIO FORMATS

8.2 Supported Audio Encoding Formats

8.2.1 Supported MP3 (MPEG layer III) Encoding Formats

VS1063a supports all MP3 samplerates and bitrates, in stereo and mono, both with constant

bit-rate (CBR) or variable bitrate (VBR). The following tables apply to both formats.

Symbol Description

++ Format is supported and recommended for this channel conﬁguration and bitrate.

+ Format is supported.

x Format is supported but use is strongly discouraged for quality reasons.

v Format is supported but for best quality lower samplerate with same bitrate is recommended.

< Format is supported but lower bitrate will give same quality.

- Format exists but isn’t supported.

Format doesn’t exist.
