Embedded MP3 Decoder |
Product Highlights
- MPEG II Audio Layer III (MP3) Decoder
- Popular CPU support: ARM, MIPs, TI, etc.
- Size and Performance optimized
- Conformance tested
- Decoder accuracy to within 1 bit of floating point
- Bit rates supported (in bits per second): Free, 8k, 16k, 20k, 24k, 32k, 40k, 48k, 56k,64k, 80k, 96k, 112k, 128k, 160k, 192k, 224k, 256k, and 320k
- Sampling frequencies supported (samples per second): 16k, 22.05k, 24k, 32k, 44.1k, and 48k
- Very portable. Majority of code is in C language (an all 'C' version exists).
- Decoder runs as stand alone application or can be integrated into RTOS.
- If targeted toward a non-wait stated target, can be made much more efficient.
