Tune It! is a piece of software that helps musicians to tune their instrument. It can also be used to monitor the pitch during live performance.
Tune It! is based on a original and very accurate pitch detection algorithm. It can tune a wide range of instruments such as guitar, bass, piano, flute, violin, saxophone, etc…
Tune It! is available for both Windows and Macintosh platforms. It can be ran as a standalone application or as a plugin within a VST or AU host.
Features:
- Automatic note recognition from A-1 up to A6.
- Programmable A440 reference from 400 to 480Hz (step of 1Hz or 0,1Hz).
- Programmable Precision
- The highest precision, the finest tuning.
- The lower precision, the lower latency (suited for tuning control during live performance)

PyKaraoke is a free karaoke player for Linux, FreeBSD, NetBSD, Windows, OSX and GP2X.
You can use this program to play your collection of CDG, MIDI and MPEG karaoke songs. No songs are provided, you must obtain these from elsewhere.
Visit here to find out more about what a CDG or MP3+G file is. In short, CDG is the format of professional karaoke CDs. These CDs can be ripped to your hard disk, and turned into a .mp3 file together with a .cdg file. This player gives you the ability to play those mp3+cdg files.
PyKaraoke Features:
- CDG (MP3+G, OGG+G, WAV+G) playback – Play standard CDG karaoke files

This is a “musical spectrum”, displayed accordingly to how the spectrum is divided in music (notes, semitones, etc).

A Mac OSX GUI frontend for open source audio codecs. There is an older Windows version available as well.

Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.
The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET, Java, Python and Pascal are provided.
