Audio SDK
for MPEG, PCM, WMA & AMR
Encode & decode MPEG format content with C++ support for DirectShow on Microsoft Windows
Create & playback MPEG Layer 1/2, MP3, PCM, LPCM, AAC, HE AAC, AMR and WMA
The MainConcept® Audio Software Development Kit (SDK) consists of audio encoders and decoders for Low Level and DirectShow on Microsoft Windows. It supports popular audio formats including MPEG, PCM, AAC, HE AAC, LPCM, MP3, AMR and WMA. The SDK is compliant with common media, devices and workflows ranging from file to live transcoding, professional broadcast and streaming, as well as a wide range of consumer-electronic products.
This holistic solution to creating and playing MPEG format files comes with the quality and peace of mind you only get using technology from MainConcept, the pioneers in encoding and decoding technology.

Product Highlights
MPEG Audio Encoder/Decoder
Audio encoding into MPEG-1 (ISO/IEC 11172-3) and MPEG-2 (ISO/IEC 13818-3) streams. The corresponding decoder enables you to playback MP3, MPEG-2.5 and LPCM audio streams. MP3 (MPEG-1/2 Layer 3) is the most widespread format for audio playback currently on the consumer market and is supported by most mobile device manufacturers.
AAC Encoder/Decoder
Encode and decode MPEG-2 (ISO/IEC 13818-7) and MPEG-4 (ISO/IEC 14496-3 including Amd.1:2003 – HE AAC v1 and Amd.2:2004 – HE AAC v2) AAC audio streams. The AAC (Advanced Audio Coding) format is predominantly used with HEVC/H.265, AVC/H.264 and MPEG-4 Part 2 video streams that are muxed into the MP4 container, required for mobile devices and streaming workflows. The AAC Encoder SDK comes with a MainConcept AAC Encoder and a Fraunhofer AAC Encoder. The latter is optimized for adaptive bitrate streaming formats. The AAC Encoders as well as the AAC Decoder support up to 7.1 channels.
(Also available as a standalone product.)

AMR Encoder/Decoder
Software-only AMR encoding and decoding components are available in narrow and wide band. AMR (Adaptive MultiRate) is a speech codec with variable bitrates standardized by 3GPP and ETSI. It is predominantly used for mobile devices, such as smartphones together with MPEG-4 Part 2 or H.264/AVC video streams.
PCM Audio Encoder
Support for DVD LPCM, AES3 PCM's and HDMV PCM (for AVCHD and Blu-Ray). The PCM audio encoder can be used with the muxer to put PCM audio tracks into DVD, MPEG-2 Transport and MXF Streams. It also supports AES3 382 for XDCAM HD and AES3 311 for IMX.
WMA Encoder/Decoder
Encode and decode audio streams into a WMA (Windows Media Audio) compliant file format. By using the MainConcept ASF (Advanced Systems Format) Muxer, the WMA streams can be muxed with VC-1 video streams.
