Hi Christopph,<br>
<br>
did you enable the preference to quick start sounds?<br>
<br>
Although there seems to be a delay before the sound starts but it
seems faster than 2 + 2 print it.<br>
<br>
And [[AbstractSound scaleTest play] timeProfile] fork. is faster
than your example (79 vs. 92ms vs 139 w/o quick start)<br>
<br>
Cheers, <br>
<br>

<p>Hi all!</p>
<p><br>
</p>
<p>As I'm currently developing a small project that uses sounds
in Squeak, I have collected a number of questions about the
Sound package and am hoping to find some answers here. Even if
you are able to answer one or two questions only, I will
appreciate your help! :-)</p>
<p><br>
</p>
<div>1. What is the difference between QueueSound and
SequentialSound? Roughly speaking, they both appear to do the
same. AbstractSound >> #, uses SequentialSound whereas
QueueSound might be thread-safe. Is there any reason why the
two are not unioned into a single class?<br>
</div>
<div><br>
</div>
<div><span style="font-size:12pt">2. Why could</span><span
style="font-size:12pt"> my coffeeCupClink be broken? It's
already the second image in which I, after playing around a
bit with sounds, managed to break that sound by accident. In
both affected images, Beeper beep just does not beep any
more. However, all other SampledSounds still sound fine. <span>SampledSound
initialize and VM restart didn't help. I even tried to
find out what's going wrong with the help of comparative
debugging of #play, but I did not discover any
meaningful difference ...</span></span></div>
<div><span style="font-size:12pt"><span><br>
</span></span></div>
<div><span style="font-size:12pt"><span>3. SoundService/<span>SoundPlayer/SoundSystem
are not thread-safe, are they?</span></span></span></div>
<div><span style="font-size:12pt"><span><span><br>
</span></span></span></div>
<div>4. Why does it take so much time to start the SoundPlayer?
I could reproduce this in two images using:
<span>[[PluckedSound default play] timeProfile] fork. In both
cases, the image was busy for ~150ms. If another sound is
already playing, #play is fast. According to the
TimeProfileBrowser, #newProcess eats up all the time (see
attachment), but can this really be true? Can you reproduce
this on your machines or could this be a Windows-specific
thing?</span></div>
<div><span><br>
</span></div>
<div><span>5. Is there any built-in way for loudness
normalization (as opposed to "normal" volume)?</span></div>
<div><span><br>
</span></div>
<div>6. Can you recommend any further resources in Squeak for
other sound concepts such as ring modulation,
sawtooth/triangle/square waves, or also other musical
instruments? For example, there are flutes and oboes, but I
did not find a piano sound. Would it be possible to build one
as a combination of FMSounds or are these instruments more
sophisticated to program?</div>
