Creating Sound Sets
Individual sounds should be created as Microsoft compatible WAV files. The
P110 supports 8, 16 and 24 bit mono or stereo data. The sample rate
should be 22,100Hz if you want to play two samples simultaneously. You
can use CD quality wave files (44KHz sample rate) but the P110 will only be
able to play one sample at a time. For engine sounds, the sample rate
should be kept as low as possible while maintaining a good quality idle
sound.
There are three distinct files for the engine – a start sound, a run sound and
a stop sound. These should all be at the same sample rate. Also to prevent
an audible click as the sounds transition from one to another, they should
all start and finish at zero amplitude. This is easily achieved with a wave
editing tool such as Audacity.
The sounds for a sound set should be copied to the root directory of the SD-
Card and titled as followed:
•
sound1.wav – Sound number 1
•
sound2.wav – Sound number 2
•
sound3.wav – Sound number 3
