By Silhwan Hyun. TBASSPlayer is a Delphi component, which helps you make music players easily with the power of BASS audio library (bass.dll, basswma.dll, bassmidi.dll and basscd.dll). Visit http://www.un4seen.com if you want to know more about BASS audio library. TBASSPlayer can play all the file formats supported by BASS audio library such as

• stream files (WAV, MP3, MP2, MP3, Ogg Vorbis, AIFF, WMA format)
• music files (MOD, MO3, IT, XM, S3M, MTM, MOD, UMX format)
• Winamp 2 DSP plug-ins
• MIDI files (MID, MIDI, RMI, KAR format)
• CD Audio tracks
• URL stream (files from the internet and Shout/Icecast)

TBASSPlayer also supports "BASS add-ons" - plugin modules designed for BASS audio library which enables the playback of additional file formats. TBASSPlayer supports Winamp visualization plug-ins and Winamp DSP plug-ins also without the need of any external library to drive them. So you can enjoy the power of numerous Winamp plug-ins with that of BASS audio library.

The DSMixer component manages playback of audio files enabling per channel control of volume, pan, pitch, fading and also access to each channel's audio data in PCM format while playing.

New Audio Components for Delphi

New Audio Components (NewAC) are designed to help your Delphi programs to perform different sound-processing tasks. With NewAC you can play audio stored in different formats (wav, Ogg Vorbis, FLAC, Monkey Audio, WavPack, MP3, Windows WMA, DTS, AC-3). The playback is performed in the background, and although you application can control it (stop, pause, move forward and backward, play in a loop) it can perform some other tasks while audio plays. You can play sound not only from external files, but also from sound resources embedded into your program, and, in fact, from any stream providing audio data. But NewAC not only allows you to play sound. You can acquire audio data from such input devices as microphone or CD and encode it into any of the audio formats mentioned above. You can also extract multi-channel audio data from CD/DVD images and VOB files. While playing audio stored in a file or while writing audio content to a file you can manipulate tags supported by the chosen audio format. Apart from all that NewAC can perform some audio-editing tasks, like mixing and concatenating audio streams, selecting fragments of streams, performing samle rate and bits per sample conversions.

In other words with NewAC you can perform wide range of audio tasks: from adding audio notifications capability to your program to writing a sophisticated audio-recorder with sound conversion and editing capabilities. And, I just forgot to mention, NewAC is free with source available.

Some of the components, like Ogg Vorbis, FLAC, WAVPack require additioan third party DLLs. You can download them in a precompiled form below.

By Boian Mitov. The OpenWire AudioLab is a set of components, based on OpenWire 3.x for fast audio processing. They allow audio capture, processing and playback with zero lines of program code. AudioLab is a subset of a larger component development project . As the scope of the project expanded the AudioLab was separated as a logical stand alone subset of components for audio processing. AudioLab supports both the old fashion Wave Win32 API, Audio ACM, and the latest DirectX Media Objects (DMO) and DirectShow, and even allows if needed any mixture of them. The developer can choose to go with any of them, to use all, or can switch from the one to the other at any moment. The components hide the complexity of both approaches, and make them look almost identical from the users prospective.
