Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
AudioMove is a handy GUI-based batch audio file converter/copier program. It can convert various audio file formats to WAV or AIFF format (using libsndfile), and do high-quality sample-rate conversion at the same time (using libsamplerate). It is multi-threaded for maximum throughput, can handle thousands of files per batch, and does recursive directory scans.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
Switch is an easy-to-use sound file converter which can convert audio files from many sources into MP3 or WAV format. A variety of different audio file formats are supported for input, including WMA, MOV, and AIFF formats. MPEG Layer-3 encoding is done using the LAME codec, and provides complete control over mode and bitrate selection. Wave encoding allows the user to cconfigure encoding technique, bit rate, sampling rate, and number of channels. It can also play tracks prior to conversion.
Oggify is a program that was written to help manage and convert FLAC audio files into other formats. It ships with MP3 and Ogg Vorbis support. It is intended to allow a user to have a directory tree of FLAC files, and be able to update a tree of MP3 or Ogg files as they add new FLAC files. It has an easy command-line interface with a variety of adjustable settings. It also features a plugin architecture to make it easy to add support for more formats.
Max is an application for creating high-quality audio files in various formats from CDs or files. When extracting audio from CDs, it uses cdparanoia. Once the audio is extracted, it can generate audio in over 20 compressed and uncompressed formats including MP3, Ogg Vorbis, FLAC, AAC, Apple Lossless, Speex, AIFF, and WAVE. It can also convert from one format to another. For many popular formats the artist and album metadata is transferred seamlessly between the old and new files. Max is integrated with FreeDB to permit automatic retrieval of CD information. For MP3, FLAC, Ogg FLAC, Ogg Vorbis, AAC, and Apple Lossless files, it will write this metadata to the output.
dirogg is a small script to migrate your entire music collection to the Ogg Vorbis format. It's a recursive script, meaning that you run it from the root of your music collection, and it will automatically convert your MP3 files to Ogg Vorbis (ogg) files. If you wish, it can also remove your MP3 files after conversion.
XO Wave is a digital audio workstation designed to meet the needs of audio and video professionals, with a focus on CD mastering and audio for video work. XO Wave provides professional-grade capabilities for manipulating audio, with a familiar and elegant interface. It supports direct recording from any Core Audio device (ALSA/Jack/OSS on Linux), importing and exporting files in a variety of formats (including songs from iTunes playlists), CD burning, multi-track editing, support for many Audio Units, and QuickTime synchronization and export.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
