The VBR and Lossless settings affect the values of Formats and FormatsCount properies.

It is only fair to warn you that this documentation is not complete.

New Audio Components (NewAC) are designed to help your Delphi programs perform different sound processing tasks.

The documentation you are reading was generated by NaturalDocs (http://naturaldocs.org) It is used to generate html documentation from source code comments and text files.

Classes that mix audio.

Delphi interface to read audio data from a CD-ROM.

Ancestor classes for all input and output components.

Classes which convert bit depth, sample rates, and stereo/mono.

Components which deal with audio hardware I/O using the DirectX API.

Classes which run filters on audio data.

NewAC interface to libFLAC.dll

Delphi interface for MP3 encoding using lame-enc.dll.

Delphi interface for Monkey’s Audio (.ape) files via MACDll.dll

Some input components which descend directly from TAuInput or TAuOutput.

NewAC interface to the Musepack codec.

OptimFROG decoder component Requires OptimFROG.dll TTALib.dll.

Utility procedures.

Registers all ACS components.

Delphi interface for mp3 playback.

Components for raw audio streams.

This unit contains classes for audio files tags handling.

TTA (True Audio codec) encoder and decoder components.

Utility types used by the various ACS Classes.

NewAC interface for Ogg Vorbis format.

This unit contains components for decoding/encoding WavPack format.

Delphi interface for Windows Media Audio (WMA) using Windows’ built-in codec.

the two streams are concatenated together and the size of the resulting stream is the sum of the sizes of the input streams.

the mixer mixes input streams and the size of the resulting stream is equal to the size of the longest input stream.

Desc: Interface to the parser to get current time.

Desc: DirectShowMotionComp include file.

Use this property to read APE v.

Use this property to add APE v.

Read this property to get Apev2 tags from the input file.

This property allows youto append Apev2 tags to the file being encoded.

Read this property to get APEv2Tags attached to the WavPack file.

Attach APEv2 tags to the file being created.

Returns the value of the Id as Integer.

Returns the value of the Id as String.

Asterisks are common characters when dealing with computer related subject matter.

Returns the value of the Id as WidString.

Desc: Broadcast Driver Architecture Media Definitions for ATSC

Desc: List of Audio device error event codes and the expected params.

This demo converts stereo to mono.

This unit contains component wrappers around several DMOs.

This unit contains the TAudioPass component.

Components which implement resampling of audio data.

This property shows the average bitrate for the ape file being played.

Use this property to set the average bitrate in VBR mode.

Read this property to get the input file’s average bitrate in kbps.

This section explains how to avoid some errors that are most often encountered by the programmers beginning to use NewAC.

The New Audio Components package is a set of components designed to handle different sound processing tasks, such as reading and storing data in different audio formats, working with sound hardware, audio streams mixing and so on.

Desc: This file defines the Ring 3 BDA interfaces that are common to all BDA network and device types.

Desc: Broadcast Driver Architecture Multimedia Definitions.

Desc: Typedefs and enums needed by both the WDM drivers and the user mode COM interfaces.

Similar to America’s Next Top Model, except for algorithms.

Read this property to get the file’s bitrate.

Set the bitrate, an additional quality parameter for the encoder.

In CBR mode sets the output file’s bitrate, in VBR mode sets the output file’s minimum bitrate.

The number of bits per sample in the input stream.

Read this property to get number of logical bitstreams in the multi-streamed file.

In some instances, Naturaldocs ignores blank space, in others, it uses it as markup.

procedure BlockingRun

In some situations, such as console programs or DUnit test units, background processing is not desirable.

The size you want some blocks to be.

Use this property to set the size of the DVI IMA ADPCM block in bytes (when using DVI IMA ADPCM encoding).

This property allows you to set the size of internal buffer in terms of playback duration.

We assume the input is 16 bits per sample.

Use this property to set the component’s internal buffer size if the defult one doesn’t suit you.

An audio disc.

A data disc.

A mixed audio-data disc.

No disc in the drive.

A disc of unknown format.

Delphi header file for CDRip.dll.

Drive is not ready.

Drive is paused.

Drive is already playing a disc.

Drive is ready to play.

In some cases you may want to start the next audio task automatically right after the previous task has been finished.

The number of channels in the input stream.

This property specifies whether the input file’s MD5 signature should be checked.

procedure Clear

Clears all the tag contents.

procedure CloseFile; virtual; abstract

Closes the file opened with OpenFile.

procedure CloseFile; override

Called by the base methods of TAuFileIn class to close the file.

procedure CloseTray

Closes CD-ROM drive’s tray.

Delphi/Kylix headers for OggVorbis software codec.

Use this property to set the index number of the codec to use when encoding.

Returns the name of the WMA codec specified by its index.

Returns the names of all the WMA codecs installed in the system.

Returns the total number of the WMA codecs available in the system.

All comments in Pascal intended for documentation should be of the parenthesis-astrisk form.

Read tags (comments) added to an Ogg Vorbis file.

Add tags (comments) to an Ogg Vorbis file.

function Compare4( S1,
S2 : PChar ) : Boolean

Used internally by ReadRIFFHeader.

This tutorial will teach you how to write input and output components for the NewAC components suite.

This unit is a demo showing how to build new input and output components for NewAC.

Set the compression ratio for the file being created.

What level you want your compression at.

Use this property to set the compression level for the APE file being created.

Sets the level of compression for a file/stream being created.

Use this property to get an information about an incoming connection.

The number of incoming connections.

To get stereo audio data from a *.wav file, convert it to mono and save to another *.wav file, we will need an instance of the TWaveIn component.

function CopyData( Buffer : Pointer;
BufferSize : Integer ) : LongWord
