203 ** GxConvolver::read_sndfile()
204 **
205 ** read samples from soundfile into convolver
206 ** the convolver is working at rate samplerate, the audio file has audio.rate
207 **
208 ** offset, length, points are based on audio.rate, delay and the count of
209 ** samples written into the convolver are based on samplerate.
210 **
211 ** Arguments:
212 ** Audiofile& audio already opened, will be converted to samplerate
213 ** on the fly
214 ** int nchan channel count for convolver (can be less
215 ** or more than audio.chan())
216 ** int samplerate current engine samplerate
217 ** const float *gain array[nchan] of gains to be applied
218 ** unsigned int *delay array[nchan], starting sample index for values
219 ** stored into convolver
220 ** unsigned int offset offset into audio file
221 ** unsigned int length number of samples to be read from audio
222 ** const Gainline& points gain line to be applied
223 **
224 ** returns false if some error occurred, else true
