FLAC Frontend is a convenient way for Windows users not used to working with command lines to use the official FLAC tools. It accepts WAVE, W64, AIFF and RAW files for encoding and outputs FLAC or OGG-FLAC files. It is able to decode FLAC files, test them, fingerprint them and re-encode them. It has drag-and-drop support too. It is tested on Windows XP SP3 and Windows 7, but should work with Windows XP SP2 or newer. It requires .NET 2.0 or later.

A Mac OSX GUI frontend for open source audio codecs. There is an older Windows version available as well.
TooLAME is a free software MPEG-1 Layer II (MP2) audio encoder written primarily by Mike Cheng. While there are many MP2 encoders, TooLAME is well-known and widely used for its particularly high audio quality. It has been unmaintained since 2003, but is directly succeeded by the TwoLAME code fork (the latest version, TwoLAME 0.3.13, was released January 21, 2011). The name TooLAME is a play on LAME and Layer II.

Features:
- High quality audio
- High-speed encoding
- Portable
- LC, Main, LTP support
- DRM support through DreaM

WavPack is a completely open audio compression format providing lossless, high-quality lossy, and a unique hybrid compression mode. For version 5.0.0, several new file formats and lossless DSD audio compression were added, making WavPack a universal audio archiving solution.
In the default lossless mode WavPack acts just like a WinZip compressor for audio files. However, unlike MP3 or WMA encoding which can affect the sound quality, not a single bit of the original information is lost, so there’s no chance of degradation. This makes lossless mode ideal for archiving audio material or any other situation where quality is paramount. The compression ratio depends on the source material, but generally is between 30% and 70%.
The hybrid mode provides all the advantages of lossless compression with an additional bonus. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a “correction” file that (when combined with the lossy file) provides full lossless restoration. For some users this means never having to choose between lossless and lossy compression!
WavPack employs only well known, public domain techniques (i.e., linear prediction with LMS adaptation, Elias and Golomb codes) in its implementation. Methods and algorithms that have ever been patented (e.g., arithmetic coding, LZW compression) are specifically avoided. This ensures that WavPack encoders and decoders will remain open and royalty-free.

Flacon extracts individual tracks from one big audio file containing the entire album of music and saves them as separate audio files.
To do this, it uses information from the appropriate CUE file. Besides, Flacon makes it possible to conveniently revise or specify tags both for all tracks at once or for each tag separately.
- Supported input formats: WAV, FLAC, APE, WavPack, True Audio (TTA).
- Supported out formats: FLAC, WAV, WavPack, AAC, OGG or MP3.
- ReplayGain analysis (album-gain and track-gain modes).
- Multi-threaded conversion process.
- Automatic character set detection for CUE files.
- Generation of the pertrack CUE file in the output dir.

This pack includes every natively supported free encoder binary for use with the Converter Foobar2000 component. The binaries are conveniently installed into a subfolder of the Foobar2000 installation folder.
Current versions of Foobar2000 will automatically recognize these encoders and no longer ask you for encoder binary location.
Included encoders:

LameXP is a free multi-format audio file converter that supports a variety of output formats, including MP3, AAC/MP4, Ogg Vorbis, Opus, as well as FLAC, and an even higher number of input formats. It also supports batch processing and can utilize multiple processor cores.
winLAME is an easy to use encoder for many audio formats, including MP3, Opus, Ogg Vorbis and more. winLAME uses the LAME mp3 encoder.
winLAME lets you read in audio tracks from CDs or encode audio files from your hard drive. The intuitive wizard-style user interface makes it easy to set up encoding settings. Multicore CPUs are used to parallelize encoding tasks.
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC and HE-AAC.

The Apple Lossless Audio Codec (ALAC) is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.
The Apple Lossless Audio Codec project contains the sources for the ALAC encoder and decoder. Also included is an example command line utility, called alacconvert, to read and write audio data to/from Core Audio Format (CAF) and WAVE files. A description of a ‘magic cookie’ for use with files based on the ISO base media file format (e.g. MP4 and M4A) is included as well.
