Aften is an audio encoder which generates compressed audio streams based on ATSC A/52 specification. This type of audio is also known as AC-3 or Dolby® Digital and is one of the audio codecs used in DVD-Video content.
- Converts PCM source audio into AC-3 audio
- Allows for setting of production metadata such as dialogue level, downmix levels, and extended bitstream information
- Supports RAW, WAV, AIFF, and CAFF input file formats
- Supports single multi-channel or multiple mono source files
- Includes several optional pre-processing filters
- Uses multi-threading and assembly optimizations to speed up encoding
foo_dsp_xover is a software digital crossover implementation that I have been working on for a while in my spare time as a hobby. It is a Foobar2000 audio player plugin that implements this digital crossover to achieve active multi-amplification.
This software needs to run on a WinXP PC equipped with a multi-channel sound card (e.g. 5.1 or 7.1 surround sound card) feeding the various voices of a multi-amplifier and loudspeaker active configuration set-up.
ANMP aims to be a versatile but lightweight audio player, just as the other hundred thousands out there. It is written in C++11. As being only a frontend, ANMP itself doesn’t know anything about audio formats and how to decode them. That’s why it uses 3rd party libraries to decode them. By using VgmStream, GameMusicEmu, LazyUSF and supporting looped songs natively, ANMP is esp. suited to play various audio formats from video games. Moreover it supports Looped Midi Tracks.
- muting multichannel audio files
- gapless playback (for most streamed audio formats)
- arbitrary (forward) looping of songs (i.e. even nested loops)
- synthesizing MIDI files using fluidsynth
- multi-channel audio rendering
- overlapping notes do not kill each other
- unrolling looped MIDI tracks
- volume response compatible to N64’s software synth
- supports an IIR lowpass filter compatible to Rareware‘s N64 games (Conkers Bad Fur Day, Jet Force Gemini)
- support for cue sheets
- support for audio normalization based on EBU R 128
- exposes basic commands via D-Bus

ChucK is a programming language for real-time sound synthesis and music creation. It is open-source and freely available on MacOS X, Windows, and Linux. ChucK presents a unique time-based, concurrent programming model that’s precise and expressive (we call this strongly-timed), dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OpenSoundControl, HID device, and multi-channel audio. It’s fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis/analysis programs, and real-time interactive music.
Extracts bass from the source signal using a linear phase low-pass filter and sends it to the LFE channel.
- fast fir processing
- adjustable filter shapes
- delay control
- mono, stereo, 3.0, 4.0, 5.0 input support
Linear phase is a property of a filter, where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. And consequently, there is no phase distortion due to the time delay of frequencies relative to one another.
Wavosaur is a cool free sound editor, audio editor, wav editor software for editing, processing and recording sounds, wav and mp3 files. Wavosaur has all the features necessary in order to edit audio (cut, copy, paste, etc.) produce music loops, analyze, record, and batch convert.
Wavosaur supports VST plugins, ASIO driver, multichannel wav files, real time effect processing.
The program has no installer and doesn’t write in the registry. Use it as a free mp3 editor, for mastering, sound design. The Wavosaur freeware audio editor works on Windows 98, Windows XP and Windows Vista.
