Lowering audio volume with Windows XP Pro. SP3's Sound Recorder result distorted audio quality?
Ant
Is it me or does lowering my WAV's audio volume result in an updated
Windows XP Pro. SP3's Sound Recorder? Is this a bug in this program or
something else?
Also, does anyone know of a good free audio program that will do batches
to lower audio volume in a bunch of old WAV files? Doing one by one is a
pain in the butt/abdomen. :(
Thank you in advance. :)

What I do for testing recording, is a "what you hear" kind of test.
It's possible for a lot of sound cards, to record what is
currently being played back. The patch panel inside the
chip, has the resources to allow you to do this.
Program #1 (playback) -----------+------> speakers
|
summing
Program #2 (record) <---------junction
You can fire up Audacity, and use it to generate a signal.
Then, leave Audacity in playback mode, sending out, say, a
sine wave.
http://audacity.sourceforge.net/
Now, go to Sound Recorder, and record the signal. Sound
Recorder would be "Program #2" in the diagram.
I think I tried to do both inside Audacity at the same
time, but it won't run full duplex. That's why I needed
two programs, to evaluate the sound hardware.
Later, load the recorded signal from sound recorder, into
Audacity, and compare the two waveforms.
Doing so, can show you various kinds of distortions, crackling,
pops, or the like. And then you can judge the distortion type,
and figure out a remedy. Or, even post a picture of the
recorded waveform, on imageshack.us, for comments.
Another kind of test signal that is handy, is an "impulse".
Using a suitable sound program, you "draw" a waveform, being
careful to not exceed the Nyquist limited bandwidth of the
system. (In other words, you can draw a square wave with
vertical edges, but due to the known bandwidth limitations
of your sound system, the pulse should really be drawn as
some kind of trapezoid. You wouldn't go out of your way,
to draw a signal, which is outside the bandwidth of the
system. Here, my rise and fall times are limited.)
----
/ \
------/ \--------
The purpose of impulse testing, is to spot the addition
of "echo" by the sound driver. My SoundMax AC97 audio chips,
had a 30 millisecond echo/delay added for "concert hall realism".
And, it couldn't be turned off. Even with the sound effects
control panel set to "None", the echo was *still* there. The
usage of the pulse, makes it easier to look 30 milliseconds
downstream, on the recorded waveform, for a tiny copy of the
pulse. It's a subtle form of "digital mutilation", which
causes a busy sound sample to "sound muddy". So if you
"hear mud", then check for an artificial echo that has
been added. The cure in my case, was to switch to a
PCI sound card, and turn the SoundMax off.

CDex is nice if you understan normalization and how to set the parameters to
get what you want.
http://cdexos.sourceforge.net/
Audiograbber is fine too and might be a bit esier to use.

Is normalization same as lowering volume? I thought normalization
basically limits the peaks?

In Audacity, when you normalize, you can set a target level. Such
as "normalize to -10dB". Then, no peak should go above -10dB.

I don;t know anything about SP3 soundrecorder.
I use Goldwave for recording and Audiograbber
for batch normalizing.

Is normalizing same as lowering audio volume? I am not familiar with
that one.

I just realized that Audiograbber won't do what you
want since it only grabs sound files from CD's.
I don't know if it would see *.wav or not.
However, if you can find a program that normalizes:
Normalizing is making all the tracks the same volume.
You can normalize to a percentage.
Say you wanted all the sound files to be of the same volume
but based on 25% of the highest volume original file,
you would normalize so that all files would come out the
same volume but only at 1/4 the volume of the highest one.

Thanks. I will try that.

A long time ago I used FakeCD to create fake cd drives.
There is probably a small program that will run on XP
that would do the same.

I suspect you could run them thru AudioGrabber after first changing the
Normalization value which I believe is 98% by default, e.g. change it to 60%
would result in an output file with a reduced volume level. AudioGrabber
allows drag-n-drop for multipule files so that's not an issue. What I'm
unsure of is will it process mp3 files or would you first have to convert
them back to wav as I've never needed to "go back" or if I thought I might
need/want to I kept the original wav also.

I think Audiograbber and Goldwave both expand to *.wav in RAM
for processing and then compress to mp3 for saving,
if stored as mp3.
