FlexiMusic Generator
$20 - FlexiMusic

1) In FlexiMusic Generator you can generate different types of sound with various algorithms using Graphs, Sine definition, wave, envelops, numbers, random, existing wave file, noise etc. 2) Sine type Sound Source: The complete waveform is created automatically using sine rule. Additionally you can have multiple sine definitions for the same sound making the sound to change gradually from one to other. The basic simple sine wave sound for drums etc can also be produced in this.2) Graph type Sound Source: This produces sound using graphs, where you actually draw the single cycle waveform shape (a small part of wave). If you know the wave shape of a particular instrument, you can draw that to produce the same instrument's sound. 3)*.wav type Sound Source directly from wav file) Here you select and use an existing wav file. By adding compensations to this wave's sound you can produce different sound using that wave sound.4) String type Sound Source: This is a synthetic string sound generator. Here you define a pattern by choosing Envelop Shape and Wave Shape, sound is produced by applying Envelop to the wave shapes, further the envelop and wave shape are modulated for width and height. You can define multiple pattern sets to produces sound varying from one shape to other. With in each pattern sets you can have single or multiple Envelop and wave shapes.5) Mouth type: Mouth type is to produces sound like multiple lips vibrating with different resonance synchronized to each other, also attach 2 small wave files as prefix and suffix. Animal sound also can be produced in this.6) Noise type: Here is a best noise Generator. There are 5 different types of noise can be produced. Multi frequency noise is produced. Noise frequency bandwidth can be set as needed. When noise follows the frequency graph and frequency range/limit very special noises come out. If you download this software remember open and try the sample noise sample.

Test Tone Generator
$30 - Timo Esser

The Test Tone Generator (TTG) turns the PC into a function generator for testing or demonstration, sound tuning, education and many other purposes.Features include: Constant and swept tones (log or lin); Many wave forms (Sine/square/triangle/sawtooth/white and pink noise with adjustable crest factor etc); Extensive scripting capabilities (Macros), dedicated Script Editor included; Preset storage and recall; Change frequencies in seamlessly real time by slider or by musical semitones; Multi sound card support; Sampling frequency up to 96kHz; Separate amplitude modulation left/right; Switches for channel on/off and l/r phase; Save test tones as WAV files for Test CDs; Externally controllable (via Windows Messages)

Tone Generator
$19.4 - NCH Swift Sound Software

NCH Sound Tone Generator lets you create audio tones, sweeps or noise waveforms using a Windows computer with a sound card or a PocketPC handheld.

Typical Applications include test tone generation in studios for the alignment of levels, calibration and testing of audio equipment or speakers, tuning music instruments as an accurate reference tone, demonstration of audio principles to students and more.

Features
~ Sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise.
~ Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card).
~ Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics).
~ Mono or separate stereo operation (ideal to create dual tones or 'beats').
~ Tone Sweeps (Log or Linear).
~ Plays tone or saves as wav file.

Fantasize Soundfont Player VSTi
$29 - Syntheway

FANTASIZE is a sample generator that works with the SoundFont2 collection (SF2), designed for creating music on your VST Host.

Parameters:
----------------
# Load SoundFont - This button is located in the middle of the interface. Click it and select a SoundFont2 instruments/drumkits bank file to load (*.SF2).
# Bank - Here you can set the patch (instrument) number in the SoundFont collection to be played by the generator.
# Preset Number - Here you can set the preset number in the SoundFont collection to be used by Fantasize.
# Instrument - Shows the name of the selected instrument. Click this area to see a full list with instruments/drumkits available in the currently loaded SoundFont collection.

Sections:
------------
# LFO (Low Frequency Oscillator): Modulation Depth, Frequency & Offset.
# ADSR envelope generator with Attack, Sustain, Decay and Release parameters and several modulation targets.
# Distortion Unit: A wave distortion effect which maps input to output values using flexible spline-based graph. Distorts the input depending on a transfer function you draw by dragging the control points with your mouse.
# MIDI Channel selector and Master Volume control.
# Delay Effect Built-in: Feedback amount & Modulation knobs.
# Reverb Effect Built-in: Customizable with user controls for: size room, width room, damping factor & mix.
# Display Signal´s Harmonic Spectrum (Freq. analyser)
# On-screen MIDI keyboard that can be played with the mouse, or keyboard (Q is Middle-C, Z two Octaves lower) The 'T' on the left of the keyboard sets Toggle Mode where each key stays held until you click it a second time.
# GLIDE control: affects pitch transitions.
# MIDI Automation: MIDI Continuous Controllers (MIDI CC) are recognized and affect 15 parameters.

Audio Multi-Tone Generator
$299 - Oleg Ya. Shmelyoff

Two-channel multi-tone audio frequency sinusoidal and noise signal generator is intended for adjusting and measuring parameters of audio equipment. Works with 16, 24 and 32 bit sound cards at sampling rate up to 384 kHz. WDM drivers support. Independent channels frequency and amplitude controls. Adjustable phase shift between channels. Up to eight oscillators per channel with separate frequency and level setting. A step of frequency setting is 0.00001 %; level - 0.001 dB; phase - 0.001 degree. The minimum coefficient of nonlinear and intermodulation distortion, precision, stability and range of frequency are limited only by quality of the used sound card. The Sweep Frequency Mode with adjustable rate in linear or logarithmic scale. Multi Oscillators Sweep Frequency Mode. Generation of noise: white, pink (1/f), Brownian (1/f^2). Mode of amplitude modulation of one channel by another. Real time signal synthesis. Recording of synthesized signals to hard disk. The demo is completely functional, but the time of sounding is limited to 15 seconds after each clicking of the "Start" button. The registration removes demonstration limitation.
