Methods > Editors > LoadSound method

Remarks

Loads a sound from a given pathname for editing purposes. The sound file can be a stream, a MOD music file or a CD audio track.

You can manage how loaded sound will be added to the existing editing session through a previous call to the SetLoadingMode method.

You can limit the range of sound data that will be loaded from the given sound file with a previous call to the SetLoadingRange method.

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

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, OPUS and WMA formats are supported natively when the MultiChannelLoadingModeSet method has been invoked with the nMode parameter set to MULTICHAN_DOWNMIX_NONE while in other cases will be converted to stereo during the loading procedure.

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

Accepted CD audio tracks format is CDA.

For loading files in RAW format use the LoadSoundFromRawFile method.

In case you should need loading a specific single channel of the audio file, use the LoadSoundChannel method.

A successful call to this method will fire the SoundLoadingStarted event followed by a number of SoundLoadingPerc events and finally by the SoundLoadingDone event.
