Remarks

Loads a song from the specified file. The sound file can be a stream, a MOD music file or a CD audio track.

Accepted stream formats are: MP1, MP2, MP3, MP4 (***), AIFF, AAC, M4A, AC3, FLAC, WavPack, ALAC, WAV, OGG Vorbis, WMA (*), ASF (**), WMV (**), W64, AU, PAF, SVX, NIST, VOC, IRCAM, PVF, CAF, Speex, Musepack, Monkey's Audio (APE), OPUS.

Formats wrapped inside a RIFF container (for example GSM 6.10, ADPCM, CCITT, etc. ) are supported if the specific ACM (Audio Compression Manager) codec is installed inside the system.

Multi-channel WAV, AIFF, OGG Vorbis and WMA formats are accepted if the output sound card supports speakers assignment and have WDM drivers installed: it's important to note that multi-channel sound files won't allow changing Tempo, Pitch and Playback rate and won't support DMO or EAX effects.

Accepted MOD formats are: MOD, MTM, S3M, XM, IT and MO3

Accepted CD audio tracks format is CDA; CD tracks can be loaded with the LoadTrackFromCD method also.

If the file is in RAW format use the LoadSoundFromRawFile method.

Other formats not supported natively may be loaded through DirectShow: for formats not supported natively you can enable the automatic usage of DirectShow on a specific player by invoking the DirectShowAutoLoadEnable method with parameter "BOOL_TRUE". After a sound or video file has been loaded, you may eventually verify if its rendering is performed through DirectShow by invoking the IsDirectShowLoadedFile method.

A successful call to this method will fire the SoundLoaded event.

The Windows Media Format modules can be installed using the redistribution setup package (wmfdist.exe) provided by Microsoft.
