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
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 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.
Helm runs in GNU/Linux, Mac OSX and Windows. Run Helm as a standalone synthesizer or as an LV2, VST, VST3 or AU plugin. Comes in both 32-bit and 64-bit versions.
CAPS is a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.
The plugins aim to combine the highest sound quality with computational efficiency and zero latency*.
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.
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.
Free open source GPL metronome (a “branch” of “Weird Metronome“) for Windows, Windows Mobile, & Pocket PC. Uses user-definable multi-voice WAV or MIDI (PC only) sounds for the beats. Has a blinker & allows user defined bpm & fine measure control.
Features:
Accurate metronome sound! No skips or variation in audio output!
Custom rhythm patterns: use it as a (very basic) drum machine
User definable beats per minute
Set measure to any length, with emphasis on any beat(s)
Over 40 MIDI voices, optionally available as WAV samples
Up to nine simultaneous voices per beat
Add your own WAV samples to use whatever sounds you like
Highly customizable parameters
Define HotKeys to perform functions such as increase tempo
Set the Maximum & minimum tempo available via the tempo slider
Listing of specialized output components that extend Foobar2000 in order to interface directly with system hardware or software output devices. Some of these are already installed by default and the remainder should be installed as needed.
By default foobar2000 uses the Windows Audio Session API (WASAPI) output in shared mode on modern versions (v1.6 and later). This means foobar2000 sends audio through the standard Windows audio stack using WASAPI unless you explicitly select another output (like WASAPI exclusive, ASIO with a plugin, or other output components).
The built in outputs and all installed output components can be selected from in the Preferences: Playback > Output > Device submenu.
Exclusive mode (in the context of foobar2000 and Windows audio) means that the player takes sole control of the audio device, bypassing the Windows system mixer for the duration of playback.
Here is what that entails, factually and practically:
What happens in exclusive mode
The audio device is locked to foobar2000 while playback is active.
No other application can play sound through that device at the same time.
Audio data is sent directly to the driver via WASAPI Exclusive (or ASIO), without Windows resampling or mixing.
The device switches to the exact sample rate and bit depth of the track being played, if the driver supports it.
How this differs from shared mode
In shared mode, Windows mixes audio from multiple applications and resamples everything to the format set in Windows Sound → Device Properties → Advanced.
In exclusive mode, Windows’ mixer is bypassed entirely, so there is no system-level resampling, mixing, or volume processing.
Technical implications
Enables bit-perfect playback, assuming no DSPs or volume scaling are active in foobar2000.
Prevents interference from system sounds, notifications, or browser audio.
Reduces latency and avoids format conversions imposed by the OS mixer.
Trade-offs and limitations
System sounds and other apps will be silent while exclusive playback is active.
If an application already has exclusive control, foobar2000 cannot start playback on that device.
Some USB DACs and Bluetooth devices have limited or unstable exclusive support, depending on drivers.
Exclusive mode does not improve audio quality if the DAC or downstream hardware already resamples internally.
GNUitar is guitar effects software that allows you to use your PC as a guitar processor. It includes the following effects: wah-wah, sustain, distortion, reverberator, echo, delay, tremolo, vibrato, and a chorus / flanger.
