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
Features
- 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.
