By Milenko Mitrovic. This is a Component Pack for Delphi 6/7 that is able to do various DSP Transformations on 8/16/24/32 Bit PCM integer and 32Bit PCM Float Buffers. Some Filters, like Amplify, 3DSound, BitRate Conversion and the FFT (which is used by the Equalizer, Spectrum Analyzer, ...) are optimized to use SSE/3DNow and extended 3DNow instructions.

Included are also Wrapper components for all MS DMO Filters (available since DX8). These DMO Filters can only handle 2 Channels and 16Bit integer or 32 Bit Float Streams.

Winamp2 Visual and DSP Wrappers, a Spectrum and Waveform Analyzer and a sample DSP/VIS Plugin API are also available in this Components Pack.

The DSP Components are release under the Mozilla Public License 1.1. Some of the Components are based on Sources under different Licenses (GPL/WOL). These Licenses are explicitly mentioned in the Headers of these Filters.

To get a better Performance the DSP Components uses John O'Harrow's FastMove, which is part of the FastCode Project and GLScene's RecyclerMM as MemoryManager replacement (needed for SSE Instructions).

By Alan Warriner. An updated Delphi and C++Builder component which allows the simple creation of sound effects within an application without the need for external audio files or resources. TToneGen achieves this by generating and processing WAV waveforms in memory.

TToneGen provides:

    * A choice of five waveforms.
    * Amplitude Modulation to allow the creation of complex waveforms.
    * Full AHDSR envelope shaping to alter the dynamics of selected waveform.
    * Frequency range of 20Hz to 20kHz.
    * Simple method of assigning musical note values.
    * Tone duration from 10mS to 30 seconds.
    * Choice of sampling rate and resolution.
    * Independent left and right volume control.

Demo application and help file included.

By Kambiz R. Khojasteh. The Wave Audio Package provides seven components for playing and recording of wave audio formats, two components for storing wave data as Delphi resources, one audio mixer component, and one high resolution multimedia timer. The package has also a set of useful functions for manipulating wave audio's.

The package's components are:

    * TMultimediaTimer: Is a high resolution timer.
    * TAudioMixer: Provides an easy interface to manage audio mixer controls.
    * TWaveStorage: Stores a single wave audio and provides some basic manipulation functions.
    * TWaveCollection: Stores a collection of wave audio's as resource and provides access to their informational fields.
    * TAudioPlayer: Plays a wave audio, which is stored in the component.
    * TAudioRecorder: Records wave audio and stores it in the component.
    * TStockAudioPlayer: Plays wave audio from a TWaveStorage or TWaveCollection component, a stream, or a file.
    * TStockAudioRecorder: Records wave audio to a TWaveStorage or TWaveCollection component, a stream, or a file.
    * TLiveAudioPlayer: Plays wave audio from user defined buffers.
    * TLiveAudioRecorder: Records wave audio to user defined buffers.
    * TAudioRedirector: Records wave audio from an input audio device and plays it back on an output audio device.

By Droopy Eyes Software. This set of audio components will allow you to play, record, and compress audio data. It is a high-level wrapper for the Windows "Audio Compression Manager" API.

Automatically convert audio data between numerous installed audio compression formats. Multiple step conversions are handled automatically behind-the-scenes. You don’t even need to know what multiple step conversions are.

    * Read or write audio streams from/to properly formatted audio files.
    * Display audio data visually in your applications.
    * Enumerate installed audio codecs as Delphi classes.
    * Enumerate installed audio hardware as Delphi classes.

Note: File-read parsing is only available for WAV files (which may contain mp3, pcm, gsm, etc).
