im not using adc~ , if i create an empty sound file (silence) with writesf~ and then if i listen to that file i listen silence, i dont listen anything, but if i open that file in a sound editor and then i save again as wav, it adds a hiss , a very subtle hiss, you need to boost up volumen to be able to listen it.</div>
<div>
</div>
<div>
</div>
<div>
I just discover this since i bought a nice speakers, before i havent realize that sound editors add that hiss.</div>
<div>
</div>
<div>
Why is that? is it possible to avoid that?</div>

With silence i mean "no sound" , Im using writesf~ because im my patch also generates sound , its not just silence.</div>
<div>
The compositions im working on are 90 % silence and the rest subtle sounds.</div>

Do the silent areas in your soundfile *look* like silence? </div>
<div>
are all the samples 0?</div>
<div>
Also, if you say subtle sounds, I suppose those are at a rather low volume. I would suggest to make them as loud as possible (so that the loudest of them is normalized to maximum amplitude (1)) and lower the volume in the end stage (the amplifier you play it back on). In other words, optimize the signal-to-noise ratio.</div>

what do you mean 'record silence' ??<br />
<br />
do you have an adc~ connected or something?<br />
<br />
if not, then why bother with [writesf~] ? just make an empty table and save the table's contents with a write message to [soundfiler].<br />

Hello, maybe this is a bit out of topic:<br />
Im using the object writesf~ to record silence , the problem i have is<br />
when i open the .wav file in a sound editor as audacity and i edit the<br />
silence.<br />
When i export my silence it adds a hiss noise, its almost unperceptible,<br />
only you can listen to it when you boost up the volumen very much, but<br />
its there.<br />
<br />
I was wondering how can i edit a pd silence without that hiss? Is there<br />
a specific software for this?<br />
Or maybe this hiss is something specific to 16 bit .wavs?<br />
<br />
thanks<br />
<br />
Sas.<br />
