<br>| Subject: [Audacity-devel] How about trying DTMF Tones?
<br>> Try generating DTMF tones using 15 hours...you might get the impression
<br>> that Audacity is hung. Progress dialog isn't taking all processing into
<br>> account.
<br><br>We have a general note about all Tone Generators in "Release Checklist
<br>not aiming for 1.4" :
<br><br>"Long tone generations (e.g. 20 minutes) can crash Audacity from time to
<br>time. i.e. the tone has not still not been generated after 30 minutes or more
<br>and Audacity is no longer responding. Consider if the theoretical 99
<br>hours, 59 minutes, 59.999 seconds generation allowed should be
<br>restricted."
<br><br>I observed the crashing on my older XP machine. On this more recent one
<br>I've been generating a 15 hour tone for five minutes in which time the
<br>"remaining time" has gone up from 20 to 45 minutes and CPU is
<br>about 15 -20 %. This isn't really useful. Should we escalate to main
<br>checklist with the intention of doing something about it e.g. generate
<br>a short tone and essentially repeat it (job done instantly)?

</div>Hi Zachary,
<br><br>When you exported, were you trying to mix the 4 tracks into one during
<br>the export? Or were you trying to export to 4 individual files? If the
<br>latter, did you use Export Multiple?
<br><br>Also, you mentioned that you could not export to 24-bit AIFF. Did you
<br>happen to notice the Options button on the export window? Even though
<br>the file type dropdown says 16-bit, you can change what actually happens
<br>via the Options button.

Greetings. I wanted to help with the audacity development process, and "On Vista, if no input device is connected <del class="diffchange"></del>such as a microphone, clicking Help > Audio Device Info causes a crash." caught my eye because it looked easy to fix, maybe a good place to start.<br><br>So I fixed it, patch attached. I wasn't sure if "as plain text attachment" meant I should append .txt, so I did just to be safe. I also the modified .cpp just in case I patched wrong. <br><br>Summary: Checks to make sure both a playback and a recording device were found before moving on to mixer tests.<br><br>I also updated the wiki with information about the bug that I found out while fixing, to help someone else if my patch is not accepted.<br>---<br>

<br>> When I saw the subject line, I thought this might be about a different
<br>> feature: It would be great if you could load up some files for viewing,
<br>> change the underlying file with another program, and select "refresh" or
<br>> "reload" to see the changed version. A more elaborate form of this is to
<br>> allow a program to specify input files, a region of time, and track view
<br>> parameters via some sort of descriptor file. For debugging audio
<br>> software or browsing experimental data, it's really great to have a
<br>> visual display, but setting up the view over and over can be a pain.
<br>> Does anything like this exist?
<br><br>1) Would Mod_Script_Pipe help here?
<br>2) Need to overcome operating system limitations on writing open
<br> files? I've never been able to edit a WAV file Audacity is reading
<br> directly (aliased) with other programs.

</div><br>Slight cross-purposes :=) I meant linkage was on when I was testing my

<br>name a type. The point is that is shouldn't name a type - it will either
<br>be a compiler attribute specifier (__dllexport,

<br><br>I've made a tiny fix, a nit rather than a real problem, in sequence.cpp,
<br>changing '-b-1' to '-1-b'. Why? Because b is unsigned, so '-b' is also
<br>unsigned, so -b-1 is actually a very large number. It all worked before
<br>because when that's converted to an int the large number is treated as
<br>negative, but swapping the order is better practice and fixes a warning.
<br><br>In latest CVS the green blobs still only progress if we are doing
<br>something to cause repaints, e.g. dragging the size/height of the wave.
<br>In your block-update-code you should check the time after reading each
<br>block, and force some painting if it's been a while (0.2s?) and is
<br>needed. This would make it a lot clearer what's going on. For me this
<br>is more urgent than the other extensions.
<br><br>Could you also look at these warnings (below) and fix the ones which
<br>belong to you? Thanks.
