Competent Audio (CA) is an audio engine suitable for video games. It is written in C, but is designed for interoperability with other languages. Windows and Linux binaries for x86 and amd64 are available. CA uses a machine graph model with support for arbitrary numbers of machines, limited only by the available system resources: - Samplers play back audio clips. - Mixers combine audio signals and optionally perform signal processing. - Sinks send audio signals to an output...

Reads audio from Windows audio interface or wave file and creates a continuous spectrum display. Command line support for generating sine, square, triangle and sawtooth wave files. Uses biquad IIR digital filters for frequency detection, plus digital lowpass filters for output extraction. Highly configurable. 60+ FPS with suitable hardware.

Adds Sony LDAC, aptX, aptX HD, AAC codecs (A2DP Audio) support to PulseAudio on Linux. This repo is a fork of PulseAudio Bluetooth modules. Added support for manual (expert) configuration for SBC codec parameters. You can use the parameters to override and fine-tune the default SBC codec config and manually setup configurations like SBC XQ, or Dual Channel HD mode. More info about SBC configuration options can be found at LineageOS documentation. Also, there is an interactive calculator and...

The SoX Resampler library `libsoxr' performs one-dimensional sample-rate conversion—it may be used, for example, to resample PCM-encoded audio. It aims to give fast and high quality results for any constant (rational or irrational) resampling ratio. Phase-response, preserved bandwidth, aliasing, and rejection level parameters are all configurable; alternatively, simple `preset' configurations may be selected. An experimental, variable-rate resampling mode of operation is also included.

Various reference programs to read baseband I/Q sample data from a Funcube Dongle Pro+ (FCDPP) software defined radio (SDR) hardware front end, demodulate the data stream and send it to the host's audio output port. Programs are present to demodulate AM, CW, FM and SSB (USB, LSB) streams. Also included is a program that writes FCDPP sample data to its standard output (stdout) port. The programs require the qthid program to control the FCDPP frequency and gain (also available at sourceforge.net. Search for: qthid). Recent activity (10/2014): Added test programs used to construct fun2ssb. ...

Gtk+ DJ; friendly GUI for generating great-sounding playlists across large music collections. Song matches are based on BPM, frequency, and user categories ('color' and rating). Works with mp3, ogg, and wav.

WAV Speech Enhancer can be used to improve the signal to noise ratio of bad quality speech recordings: - Dynamic expansion - Pink noise attenuation - Low frequency noise (50-60Hz) suppression

Ceasar is an open-source multi-frequency tone gereator for UNIX, initially Linux. By default it contains standard DTMF tones together with C5 (bluebox) tones.

Tune is a note/chord detecting program for use with guitars, pianos, or voices. It uses an FFT to analyze incoming sound and computes the root frequency.

Funiculus is a guitar tuner for the iPhone. It analyzes the frequency of a note played and provides feedback to the user.

FFT Spectra is a tool for visualization of frequency spectra of an audio signal. What is it good for? For instance, you can verify whether you are able to sing and whistle in-tune or tune your guitar.

RECWAV gives a processor-efficient display of the spectrograph of an audio file, showing the energy in the sound at each moment and frequency. It was originally developed on a '286 under DOS and now also runs under Linux with svgalib.

This program is able to analyze sounds heard by your PalmOS device (e.g. LifeDrive), finding their frequency. Its purpose is to tune musical instruments.

Sculptor is a phase-vocoder-based package with real-time capabilites. You can use it to fiddle with soundfiles in the frequency domain, changing pitch and duration independently.

A simple C program for GNU/Linux systems to synthesize a sound signal with binaural beats: when listened to with headphones, the distinct frequencies of the two channels interfere in the brain to produce a difference frequency in the EEG range.

A program that generates music (WAV-like files) from a specification of tones in absolute frequencies, rather than the normal well-defined tones. The specification list all notes, their length, frequency and amplitude and the program generate a mix of all

1) the samplomatic: gathers sounds from environs; frequency spectrum analasis; write wav samples 2) the syncotron: autonomous sequencer plays audio stream; listens on network for commands 3) syncotron client: curses-based UI for talking to the syncotron
