SW320023-1HPM - PIC32 AAC Decoder Library for Harmony

Part Number: SW320023-1HPM

Summary:

The AAC algorithm is designed for 80MHz or greater PIC32 MCUs, and supports both PIC32MX and PIC32MZ devices. This code requires 62MIPS peak 34MIPS average performance, 61KB Flash and 12KB RAM without frame buffer memory for operation on the MCU.

Product Features

    Microchip offers AAC Decoder library both in non-modifiable binary code and source code formats that enables usage on high performance PIC32MX devices. The decoder is a low complexity decoder AAC – LC with support for parsing ADTS headers only.

    • The ADTS header Audio Data Transport Stream (ADTS) is a format, used by MPEG TS or Shoutcast to stream audio
    • Not all *.aac audio files will play using this decoder, since not all follow the same header or AAC – LC format for encoding
    • Music with ID3 tags does not decode
    • AAC_LTP is not supported
    • Only music with AAC-LC v4 format WITHOUT ID3 tags is supported
