[LAD] Undeliverable mails for Rui

Hi Rui :)

after it failed to send the wanted test to you, because of it's length,
I'm blocked :D.

Sorry LAD list, Rui is waiting for this test and I don't know how to
reach him, while I'm blocked.

Cheers,
Ralf

Hi Rui :)

first I got some noise references.

spinymouse-sudo@email-addr-hidden:/usr/src/qtractor/noise$ wget
http://upload.wikimedia.org/wikipedia/commons/6/66/Whitenoisesound.ogg
http://upload.wikimedia.org/wikipedia/commons/6/6c/Pink_noise.ogg
http://upload.wikimedia.org/wikipedia/commons/c/c9/Brownnoise.ogg

Then I set the CPU frequency scaling to "Performance" and launched JACK
and after JACK I run Qtractor.

spinymouse-sudo@email-addr-hidden:/usr/src/qtractor/noise$ jackd -Rdalsa -dhw:0
-r96000 -p512 -n2 -Xseq
spinymouse-sudo@email-addr-hidden:/usr/src/qtractor$ qtractor -v
Qt: 4.4.0
Qtractor: 0.4.3.1409
spinymouse-sudo@email-addr-hidden:/usr/src/qtractor$ qtractor

I Imported the three noise.oggs.

Qtractor didn't show the waveform for the brown noise recording
completely, I don't know the reason why and I never had this bug or user
error before, but it's also the first time I used 0.4.3.1409. I tried to
record it 2 times.

I did stereo recordings for the mono clips too, because this shouldn't
cause any changes for the audible result.

Okay, a completely new problem occurred. There's an audible loss for the
quality of the sound, but in this case because of an understandable
reason. The .ogg files are to loud with faders set to +- 0 db. The
important thing with this is, that the loss of the sound quality for the
white noise is comparable with the kind of loss I've got when doing a
recording of music, even if the maximal signal level is under -3 dBFS.
So it doesn't matter if the meters are Full-Scale Square wave or
Full-Scale Sine Wave meters. Anyway, I wonder where the boost is from.
When I recorded music by connecting Qtractors outputs to its inputs
both, source clip and target clip were 96-24-stereo.wav files. There
never was a visible difference for the volume.

Before I go on comparing music recorded by Qtractor and Audacity, I want
some information because of the strange level for the .ogg files from wiki.

The qtractor session is attached as tar.gz. I suppose you'll have a
directory /usr/src/qtractor too, thus you just need to add a directory
/usr/src/qtractor/noise.
