AAC-LC Encoder / Decoder for 2 / 5.1 Channels

Product Overview

AAC-LC is an international standard for lossy compression audio codecs, widely used as a distribution format for music data and a digital broadcast audio format.

This product is a software IP with low power consumption, low memory consumption, and can be embedded in a short period of time, suitable for products such as portable music players, car audios, digital cameras, camcorders, and voice guidance.

Model Numbers

Encoder :  TM13725

Decoder:  TM13726


  • Low power consumption operation by reduction of arithmetic processing with TMC’s original algorithm “DMNA”.
  • TMC’s unique tuning provides high sound quality from low bit rate to high bit rate.
  • Can be implemented in various processors including ARM.
  • Easy to embed by simple API interface, contributing to shortening the development period.
  • Thread-safe library, simultaneous encoding and decoding of multiple streams.
  • Compliant to the ARIB standard, 5.1ch version and HE-AACv1 (for 1-Seg audio) included version are available.
