Protoplug ~ Scriptable Audio Plugins

Posted by tom2tec on

Create audio plugins on-the-fly with LuaJIT.

Protoplug is a VST/AU plugin that lets you load and edit Lua scripts as audio effects and instruments. The scripts can process audio and MIDI, display their own interface, and use external libraries. Transform any music software into a live coding environment!

Cross-platform: builds for Windows, Mac OS X and Linux. This means that all protoplug scripts are compatible with these platforms and can be loaded into a huge amount of audio software (glory to JUCE).

Fast: Use the speed of LuaJIT, and perform DSP tasks as efficiently as old school C implementations.

Free and open source: Want a new feature? Add it yourself. The source is MIT-licensed and available on Github.

Cover Retriever ~ Album Artwork Downloader

Posted by tom2tec on

Cover Retriever is free software for Windows that makes it easy to add album cover art to mp3 and flac audio files on the computer.

Album cover finder

The search is based on data obtained from the file tags and processing through Google’s search engine. The drill is as easy as can be: you just have to select the folder that contains your audio files and let this app take care of the rest. You’ll have your covers in just seconds.

Tag finder

The tags search allows you to fill out audio file tags and find appropriate covers. The tags can be easily saved to the file by clicking one button. The search is based on the AcoustId service in order to get the best results.

foo_dsp_xover ~ Foobar2000 Digital Crossover

Posted by tom2tec on

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.

lossyWAV ~ Lossy PCM In WAV File Format

Posted by tom2tec on

lossyWAV is a free, lossy pre-processor for PCM audio contained in the WAV file format. Proposed by David Robinson, it reduces bit depth of the input signal, which, when used in conjunction with certain lossless codecs, reduces the bitrate of the encoded file significantly compared to unpreprocessed compression. lossyWAV’s primary goal is to maintain transparency with a high degree of confidence when processing any audio data. ~ wiki.hydrogenaud.io/index.php?title=LossyWAV

lossyWAV is a near lossless audio processor which dynamically reduces the bit depth of the signal on a block-by-block basis. Bit Depth reduction adds noise to the processed output. The added noise is adaptively shaped by default and can alternatively be fixed noise shaped or white noise depending on command line parameters. When lossyWAV processed output is compressed with certain lossless codecs (FLAC, Wavpack, Tak, LPAC, MPEG-4 ALS and WMA-Lossless) the bitrate of the output file is significantly[1] reduced compared to the lossless original.

[1]: on average, depending on content.

FLAC Frontend ~ Lossless Encoding GUI

Posted by tom2tec on

FLAC Frontend is a convenient way for Windows users not used to working with command lines to use the official FLAC tools. It accepts WAVE, W64, AIFF and RAW files for encoding and outputs FLAC or OGG-FLAC files. It is able to decode FLAC files, test them, fingerprint them and re-encode them. It has drag-and-drop support too. It is tested on Windows XP SP3 and Windows 7, but should work with Windows XP SP2 or newer. It requires .NET 2.0 or later.
