AAC HE 和 LC 音频编码器 状态: ACTIVE

产品说明

描述

– Free production-quality code is offered with production licensing. Many of the codecs are available for immediate download. Some require request. After a request is processed, download instructions will be emailed to you.

The DM355S AUDIO Codec Bundle must be used when TMS320CDM355 devices are used. This Ittiam production code is also available for free. Pleas contact Ittiam directly for support questions.

The HE-AAC and LC encoders are proven modules. The ready-to-implement HE-AAC and LC encoders reduce time-to-market because they can be treated as tested modules and integrated into a software system. TI’s encoders conform to the standard originally developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). The encoders implement the AAC low-complexity (LC) and long-term prediction (LTP) object types in addition to the high-efficiency (HE), low-memory and low-MIPS profiles which are compile-time options.

TI’s AAC is an optimized audio encoder and is xDM compliant. It is available in system tested codec combinations with Codec Engine, DSP/BIOS, DSPLink and Framework components.

特性

• Supports AAC LC object type implementations up to two channels
• Supports Audio Data Interchange Format (ADIF) and Audio Data Transport Stream (ADTS) input formats, those files encoded with ISO/IEC 13818-7 or 14496-3 compliant encoders
• Supports sampling frequency range of 8 kHz – 96 kHz as per ISO/IEC 14496-3 standard
• Supports maximum bit-rate based on sampling frequency as per standard

可用更新

• For production codecs (BASIC or AUDIO Bundles), users will be notified of updates when they are available. Downloads will be delivered via myRegistered Software (TI’s software management portal).
• For evaluation codecs, the most current version available is delivered at the time of the Evaluation request.
