AAC Encoders & tools

Here we have some some AAC encoders based on FAAC as well as tools to deal with AAC and mp4/m4a files.

exhale-V1.1.7-acd53a21 for Windows


exhale, which is an acronym for "Ecodis eXtended High-efficiency And Low-complexity Encoder", is a lightweight library and application to encode uncompressed WAVE-format audio files into MPEG-4-format files complying with the ISO/IEC 23003-3 (MPEG-D) Unified Speech and Audio Coding (USAC, also known as Extended High-Efficiency AAC) standard. In addition, exhale writes program peak-level and loudness data into the generated MPEG-4 files according to the ISO/IEC 23003-4, Dynamic Range Control (DRC) specification for use by decoders providing DRC. Changes since version 1.1.6 from May 2021: minor tuning at low SBR rates, enabled SBR coding at 22050 Hz input sample rate exhaleApp: added expert modes for loudness leveling, custom Intra frame interval. Important: Due to the missing lower-rate coding tools, the audio quality at the lowest of exhale's bit-rate modes (18 kbit/s mono, 36 kbit/s stereo) doesn't reflect the full capabilities of the Extended HE-AAC standard. Therefore, use the lowest bit-rate modes only when required. Also, please don't attempt to modify exhale's source code or to configure the command-line encoder to produce lower bit-rates. Use only existing presets and input sampling rates of 32...48 kHz. Intel 19 compiles. x86 compile should be XP friendly.

FAAC v1.30 Binary for Win32


FAAC is a command line AAC/MP4 audio encoder for Win32. This is the latest version and should be 'XP' friendly.

libFAAC dll for Win32


Standard faac dll, usable on some CD rippers and frontends. Latest version and should be 'XP'friendly.

libFAACdrm dll for Win32


Standard faac dll, usable on some CD rippers and frontends. Latest version and should be 'XP'friendly.

This CoolEdit Pro/Adobe Audition plugin does importing and exporting of AAC/MP4 streams, using FAAC 1.28 and FAAD2 2.7. Unzip the file to CoolEdit/Audition's folder.

AAC Output Plugin for Winamp 2 and Winamp 5


This Winamp plugin does exporting of AAC/MP4 streams, using FAAC 1.24

AACGain v1.9


Command line ReplayGain tool for MP4 and M4A streams based on mp3gain. This release includes the following changes: Fixed a bug in mp4v2 which caused iTunes music video files to fail with "not a valid mp4/m4a file" error. Gives a more meaningful error message when attempting to process Apple Lossless files (which are still not supported by aacgain). Built with updated mp4v2 and faad2 code. Built with latest mp3gain version 1.5.2, which includes id3v2 tag support. See the included README file for more info. By Dave Lasker.



A front-end for AACGain to enable it to work better with iTunes. Win32 only (no Mac port available). It is packaged as a Microsoft Installer (.msi) file which also installs aacgain.exe. (This updates the version of AACGain packaged with the iGain installer to version 1.9. No changes were made to iGain itself.) By Dave Lasker.
