AAC Encoders & tools

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

exhale-v1.2.1 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 from July 2023:
Fixed as part of Git commit b17f659c. Now lower-preset encodings decode almost bit-identically to those made with exhale release 1.1.9, which is good... and the higher presets are still bugfixed, which is even better.
Win32 compile is XP friendly. Intel 19.0 compiles.

exhale-v1.2.1-BA_MORE_CBR set (CBR, experimental!) for Windows


As above, except that these were compiled using the BA_MORE_CBR macro which forces more constant bit-rate (CBR, experimental!). Not recommended for archiving. Win32 compile is XP friendly. Intel 19.0 compiles.



fdkaac-1.0.5 built against fdk-aac 2.0.2. VC-2015 compiles, Win32 version is '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.

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.
