ISSE ~ Interactive Source Separation Editor

Posted by tom2tec on

In applications such as audio denoising, music transcription, music remixing, and audio-based forensics, it is desirable to decompose a single-channel recording into its respective sources. To perform such tasks, we present a new software tool to perform source separation by painting on time-frequency visualizations of sound. Initial results shows the software can achieve state-of-the-art separation results compared to prior work.

Features:

  • Source separation
  • Denoising
  • Painting
  • Interaction

Nootka ~ Learn Classical Score Notation

Posted by tom2tec on

Nootka is an application to help learn classical score notation. It helps in understanding the rules of reading and writing scores and helps with developing skills of playing and singing notes.

Simply: users looks at piece of a score, plays it, while Nootka is listening to it, checks and shows was it played well. All in real time.

Features:

  • interactive interface to discover the rules of musical notation
  • exercises with possibility to create own sets
  • accurate method for detecting sung and played sounds
  • natural sound of guitars
  • clefs (treble, bass and others) and grand staff
  • analysis of results
  • different kinds of guitars and their tuning

foo_dsp_delta ~ Foobar2000 Noise Sharpening

Posted by tom2tec on

A digital signal processor that makes dull songs sound sharper, as in brighter.

Strictly speaking, nobody really needs this DSP. It’s just that some people like the effect. If you want to compensate deficiencies in your playback equipment or listening environment, the convolver or the equalizer are more appropriate tools. ~ HA post

There are four interrelated DSPs enclosed, only use the last one, Noise Sharpening.

Noise sharpening can/should be used alone. ~ HA post

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.
