Post From: WAV file trouble, bitrates/encoding?

hi friends, I'm experiencing trouble with some wav files I want to use in my advanced custom study with sc.PlaySound. Troubleshooting Steps: 1. Using General Settings > Alerts/General 3 I can successfully test/play/hear default sierra wav files (airplane.wav, applause.wav, etc) 2. I can also use these default sounds from within my study with sc.PlaySound. 3. I downloaded from the internet some different wav files, like buzzer sounds (for a stop) and cash register (for a target). Some will play in the Alerts/General 3 tab and some will not ---and furthermore, those that do play in the test tab have this weird delay where it seems to cut off the first half-second or so of the audio so it sounds like I only get half a "ka-ching" for a target. bizarre. So, 1. I don't know why some wav files play, while others do not and 2. I don't know why some that play, only seem to play half the audio file. My suspicions are that Sierra is particular about what wav files it uses and what I'm trying to use is not either in a particular format/bitrate or a different encoding. I used Audacity (an open source audio program to try and see what WAV files Sierra likes, but so far no dice in figuring this out) WAV files can have a number of formats/bitrates: 8 kHz, 8 Bit, Mono 8 kHz, 8 Bit, Stereo 8 kHz, 16 Bit, Mono 8 kHz, 16 Bit, Stereo 16 kHz, 8 Bit, Mono 16 kHz, 8 Bit, Stereo 16 kHz, 16 Bit, Mono 16 kHz, 16 Bit, Stereo etc... AND WAV files can be encoded a number of different ways. WAV (Microsoft) Signed 16-bit PCM Signed 24-bit PCM Signed 32-bit PCM Unsigned 8-bit PCM 32-bit float 64-bit float U-law A-law IMA ADPCM Microsoft ADPCM GSM 6.10 32Kbs G721 ADPCM 16kbs NMS ADPCM 24kbs NMS ADPCM 32kbs NMS ADPCM Audacity has an export function which should be able to convert my sounds into something Sierra likes, but I'm not sure what Sierra will like. Anyone out there know the format/bitrate and or encoding that makes Sierra happy? Thanks! |
