LEADTOOLS provides Advanced Audio Coding (AAC) encoders, decoders, and transcoders for DirectShow and Media Foundation.
These codecs compress and decompress audio data using the AAC compression standard (ISO/IEC 13818-7), which is
designed to be the successor of ISO/MPEG Audio Layer-3 (MP3).
AAC, also known as MPEG-2 Part 7, is a lossy digital audio encoding compression standard.
AAC typically delivers high-quality audio at a lower bit rate when compared to other audio encoding standards such as MP3.
Full support to encode, decode, and transcode audio data using the ISO/IEC 13818-7 AAC standard within MPEG-4 and MPEG-2 containers
Supports both variable and constant bit rates
Correct audio and video synchronization issues with automatic timestamp drift correction
Selectable output channels
Force stereo output option in the decoder
5.1 and 7.1 surround sound
Raw and ADTS stream formats
Output sample frequency selection
Cut-off frequency option
Includes .NET (C# & VB) and C DLL libraries for 32 and 64-bit development
AAC Compared to MPEG-1 Layer 2
AAC is the one of the most powerful audio codecs available today. The near CD quality MPEG-1 Layer 2 audio codec
widely used in digital video applications delivers high-quality stereo at 128kbit/s/channel
while MPEG-4 AAC offers the same quality at 64kb/s/channel.

The LEADTOOLS Streaming Module is perfect for developers who need to stream audio and video over the Internet or corporate networks for a wide variety of applications. This module adds on to the LEADTOOLS Multimedia SDK and includes the Media Streaming Server, a high-level framework for implementing professional multimedia streaming servers that can stream any file to any device. The Streaming Module also provides a programmer-friendly set of peer-to-peer tools for creating video conferencing and security/surveillance applications. In addition to the SDK features, the Streaming Module bundles together several of LEAD's world-class audio and video codecs that will lower costs and improve user experience through reduced bandwidth requirements and high-quality playback.
The LEADTOOLS MPEG-2 Transport Module adds advanced MPEG-2 Transport and MPEG-2 Program streaming, playback, capture, and conversion capabilities to the LEADTOOLS Multimedia SDK. Developers can utilize robust UDP and TCP streaming with DVR and KLV metadata to create a wide spectrum of applications, including security systems, HDTV playback, and UAV ground stations.
NOTE: LEADTOOLS Audio Codecs are very diverse and cover the gamut of multimedia features and technologies. Many codecs are included with the base SDK products above, while some can be added á, la carte or bundled together with various add-on modules. See the Multimedia Product Comparison Chart for more details on how to obtain each audio codec.
