Re: [SoundComp-Develop] me stupid...

OK so you can play 32bit floating point .wav files. The one that does not play is a 64bit double precision one; that is SoundComp's internal format. Audacity can read, display and play them, Windows media player and VLC cannot.

I am still puzzled why it runs so slowly on your machine. It is normal for Soundcomp to draw 100% CPU (actually it is number crunching without taking breaks), but it shouldn't do that for such long times on these simple tests. I measured it and got
testTS1 13.5 s
testTS2 7.21 s
testTS3 3.2 s

testTS4 4.6 s
testTS5 4.17 s
testTS6 8.5 s
testTS7 22 s
testTS8 13.7 s

so,  roughly 10% of yours. 1.5 GB should definitely suffice. There must be a different reason for your computer being so slow at it, but at the moment I run out of ideas why. As it stands, I would not expect a .exe version to help you then. From your numbers, I would have expected you to have a total 256MB or at max. 512 MB RAM - in these cases, running without eclipse would be beneficial. Not at almost 500MB of _free_ RAM.


I take this to the list;maybe others can give their experience how long the tests run on their setup?

  I just played all 14 files (is that right?) and all of them played, but not hilbertsweep_d.wav, it's 2,116,884 bytes.

 Yes, I stopped the test before it was done, so I got a part of a file.

My system:
Win XP
3.2 GHz Intel Processor
1.5 GB RAM


Nothing open (only firefox + anti-virus, ect.):
5% CPU Usage
725MB RAM Usage

Opened eclipse (with workspace open, doing nothing):
5% CPU Usage
835MB RAM Usage

Running test:
Immideatly:
100% CPU Usage
890MB RAM Usage
eclipse.exe using 110MB RAM, 0% CPU
javaw.exe using 28MB RAM, all unused CPU

During 7th:
100% CPU Usage
931MB RAM Usage
eclipse.exe using 120MB RAM, 0% CPU
javaw.exe using 60MB RAM, all unused CPU


Right now, it is working :) I just logged off, so I don't know what happened.
testTS1 (189 s)
testTS2 (96 s)
testTS3 (37 s)
testTS4 (39 s)
testTS5 (37 s)
testTS6 (87 s)
testTS7 (287 s)
testTS8 (136 s)

total: 15 min (may not add up right, I used a different stopwatch for this)

Ok, it seems your computer is a bit overpowered by this. Mind that it's not only SoundComp, but SoundComp inside all this eclipse stuff.
Under these cirumstances I rethink the priority of an external .exe - so that you can run soundcomp alone, without the eclipse overhead.
On my PCs (2.5GHz AMD dual core, 4 resp 8 GB RAM), it takes a few seconds for all 8 tests.

Some of the .wav files are 32bit floating point stereo files. On my XP-x86 as well as my XP x64 they play fine, but chances are that at least older windows cannot play this from start.
There are also tests that produce "old-fashioned" 16 bit fixed stereo .wav files.
The 880HzSaw actually IS one of the 16bit-stereo files that media player should play out of the box. The size would be exactly 882.046 Bytes. Maybe you interrupted it prematurely (because yours is much smaller) and now have a corrupted file.

Can I get some information about your hardware/software enviromnent? I would assume the main problem might be RAM size - eclipse as many java programs being quite consuming in that respect. A standalone SoundComp tester could definitely help. My eclipse draws between 200 and 500 megs of my RAM - but I have between 4 (x86) and 8 (x64) gigs on my machines, so that does not matter for me.

Maybe you can open your windows task manager and look what is consuming RAM (there are optional columns that show per-process RAM consumption in the process list view). Unless your CPU is extremely slow, I would not consider that the main problem, even on <1 GHz you should get the tests completed in a minute if sufficient RAM is available.

Nevertheless, I will spend some thoughts about getting a starter executable integrated in the project to help in such cases. Just don't expect it to be there tomorrow or this week, but it WILL come soon enough, I will not forget about it. There may be others that have the same problem, so it must be addressed in a general way.

Right now I have been running it for about 2 min. with it using all of my extra CPU, I ended it. I got 1 file, 880HzSaw.wav, which is 197KB (is that the right size?). When I open it with Windows Media Player, it says it can't play it.
