Hello Dean,<br><br>As I said before, something was funky with my image. In a clean 3.8 image (although I have changed the SoundPlayer SamplingRate to 44100), I created a new storeWAVOnFileNamed method for a SampledSound as you suggested, and that worked! However, when I tried it with the pre-existing WAV sample I originally wanted to use, it didn't work--which led me to the following:
<br><br>"This works when creating a mono sound"<br>snd := FMSound new.<br>snd setPitch: 200 dur: 5.0 loudness: 0.25.<br>snd storeWAVOnFileNamed: 'monotone.wav'.<br>snd := (SampledSound fromWaveFileNamed: 'monotone.wav
').<br>snd addEnvelope: (VolumeEnvelope newExponentialDecay: 0.96).<br>snd play.<br><br>"It does not work for stereo..."<br>snd := FMSound new.<br>snd setPitch: 200 dur: 5.0 loudness: 0.25.<br><br>"Turn the sound into a stereo sound and save it as a WAV"
<br>mix := MixedSound new.<br>mix add: snd.<br>mix storeWAVOnFileNamed: 'stereotone.wav'.<br><br>"Read a STEREO sound from a WAV as a SampledSound and try to modify it"<br>snd := (SampledSound fromWaveFileNamed: '
stereotone.wav').<br>snd addEnvelope: (VolumeEnvelope newExponentialDecay: 0.96).<br>snd play.<br><br>It would seem that the answer lies somewhere in how stereo vs mono sounds are handled. Ultimately, I want to use a VolumeEnvelope on a MixedSound that contains both a stereo RepeatingSound, a Left channel FMSound, and a Right channel FMSound. I am actually starting to think that will be possible!
<br><br>Thanks again. I feel like I am finally starting to "understand" Squeak a bit...thanks to a good problem that I have a desire to solve!<br><br>--Rob<br><br><div><span class="gmail_quote">On 5/5/06, <b class="gmail_sendername">

<br><font face="sans-serif" size="2">Hi Rob,</font>
<br>
<br><font face="sans-serif" size="2">This begs the question: "What version of Squeak are you running, and on what platform?"</font>
<br>
<br><font face="sans-serif" size="2">I just tried your example on Squeak 3.7-5989 on my G4 iBook (OS X 10.4.6, Squeak 3.8.12beta4U VM), and your example works fine. It writes out the tone to a file without any decay, then the SampledSound plays with the decay after reading the tone back in and adding the envelope.
</font>
<br>
<br><font face="sans-serif" size="2">Your earlier problem really is a problem. We'll have to see what the others say for future versions, but for now you could just make a new method on SampledSound, something like:</font>
<br>
<br><font face="sans-serif" size="2"> SampledSound>>myStoreSampleCount: samplesToStore bigEndian: bigEndianFlag on: aBinaryStream</font>
<br><font face="sans-serif" size="2"> super storeSampleCount: samplesToStore bigEndian: bigEndianFlag on: aBinaryStream.</font>
<br>
<br><font face="sans-serif" size="2">which would just execute the AbstractSound implementation.</font>
<br>
<br><font face="sans-serif" size="2">So, I'll need some help trying to reproduce your current problem.</font>
