PySynth ~ Python Synthesizers & Scripts


PySynth is a suite of simple music synthesizers and helper scripts written in Python 3. It is based on a synth script I found on the Web and then modified for my purposes. The goal is not to produce many different sounds, but to have scripts that can turn ABC notation or MIDI files into a WAV file without too much tinkering.

There are nine PySynth variants now: PySynth A, the oldest variant, only needs Python itself, and sounds somewhat like a cross between a flute and organ. PySynth B is more complex in sound and needs NumPy. It is supposed to be a little closer to a piano. No competition for Pianoteq of course, but a reasonable fit for keyboard music. PySynth E is similar, but an FM-synthesized e-piano so it sounds much brighter than B (slightly DX7 e-piano-like; I used the DX7 presets in hexter as a basis). PySynth S is more comparable to a guitar, banjo, or harpsichord, depending on note length and pitch. PySynth C, D, and P are subtractive synths, reminiscent of 1970s analog synthesizer voices.

The synthesizers are all monophonic, i.e. they can only play one note at a time. (Although successive notes can overlap in PySynth B and S, but not A.) However, two or more output files can be mixed together…

NoiseGator ~ Simple Noise Gate


Ever wanted to cut out background noise when talking with others on Skype? Now it’s possible!

NoiseGator is a light-weight noise gate application that routes audio through an audio input to an audio output. In real-time the audio level is analysed and if the average level is higher than the threshold the audio bypasses as normal. However, if the average level goes below the threshold, the gate closes and the audio is cut.

When used with a virtual audio cable it can act as a noise gate for a either a sound input(microphone) or sound output(speakers). Can also be used to gate noise from your own mic or play your microphone through your speakers.

REQUIREMENTS:
– Java 7 or higher for Windows.
– Java 6 or higher for Mac. Java 7 recommended.
– A virtual audio cable is required for use with VOIPs:

For Windows users I recommend the VB-Cable driver (http://vb-audio.pagesperso-orange.fr/Cable/index.htm).
Mac users can use SoundFlower.

Features:
  • Noise Gate for audio input to output.
  • Cuts out background noises when nobody is speaking on VOIPs like Skype.
  • Noise Gate your microphone to kill background noise and hiss.
  • Can be used to feed your microphone through your speakers.

meterec ~ Console Multitrack Recorder


meterec works as a basic multitrack tape recorder. The aim of this software is to minimise the interactions of the users with the computer and allow them to focus on their instrumental performances. For this reason meterec’s features are minimal. If you screw one take, start it over again! Rather than learning how to use a specific software to correct what you screw up, meterec forces you to learn and master your instrument. The good news is that previous takes are kept in history and if in the end, the first one was the best you could play, you can choose it in your final mix.

CloudTunes ~ Web Player For The Cloud


CloudTunes provides a unified interface for music stored in the cloud (YouTube, Dropbox, etc.) and integrates with Last.fm, Facebook, and Musicbrainz for metadata, discovery, and social experience. It is similar to services like Spotify, except instead of local tracks and the fixed Spotify catalog, CloudTunes uses your files stored in Dropbox and music videos on YouTube.
