PJSIP
PJSIP project
PJSIP is a free and open-source multimedia communication library written in C language implementing standard-based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. It combines signaling protocol (SIP) with a rich multimedia framework and NAT traversal functionality into high-level API that is portable and suitable for almost any type of system ranging from desktops, and embedded systems, to mobile handsets. PJSIP is both compact and feature rich. It supports audio, video, presence, and instant messaging, and has extensive documentation. PJSIP is very portable. On mobile devices, it abstracts system-dependent features and in many cases is able to utilize the native multimedia capabilities of the device. -

PerfectSineWaves
Perfect and bit-perfect PCM encoded sine wave audio test tones
In this project, a perfect PCM sine wave is one that contains a single frequency at 0 dBTP and no error harmonics at all. A bit-perfect PCM sine wave has error harmonics due to encoding quantization, but they are at the minimum level possible for the chosen encoding. The generated wave files hold a sequence of one or more complete copies of a repeating pattern. A file containing a single pattern can be played in a loop to extend the play time. Because most audio players don't loop cleanly, the included wave files contain enough complete patterns to play 2 minutes without looping. ... -

vahatraker
a live MIDI sequencer for JACK
...It relies 100% on JACK audio connection kit for input/output/synch and uses jack_capture for rendering. The GUI has similar dependencies as gnome-calculator and tracker paradigm was chosen to allow for rhythmic gymnastics otherwise hard to convey. Low level stuff was done in C and wrapped in Python. Human interfacing part of contraption employs GTK through gobject introspection and was also contrived in the language we shall no longer spam abo -

The SoX Resampler library
High quality, one-dimensional sample-rate conversion library
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. -
