MP3 Encoder / Decoder

Product Overview

MP3 (MPEG-1 / 2 Audio Layer III) is an international standard for lossy compression audio codecs and is widely used as a distribution and distribution format for music data.

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, smartphones, car audios, PCM recorders, and voice guidance.

Model Number

Encoder: TM1315

Decoder: TM1316


  • 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.
