Is there a way to measure the dynamic range of material in wavelab, harbal,
cool edit or something?

Thanks

Wavelab includes tools called Global Analysis that report Peaks, RMS Power
(including Max, Min and Average), as well as pitch, errors and DC offset.

What would accurately describe dynamic range in those?

Used dynamic range for a selection, or possible dynamic range in general?

Obviously the latter is determined by your bit depth - 96dB for 16 bit,
144dB for 24 bit. You can always select a range in either Wavelab's
analysis or Cool Edit Pro's Statistical Analysis (iirc) - the difference
between the min and max values in dB would be the dynamic range covered for
that selection.

Dedric

The problem is that people use the term to mean different things. The traditional
definition, is the difference between the loudest part of the recording
and the softest part.
It is confusing because some people define it as the loudest part compared
to the point that sound is at equal level to the noise level (noise floor).
Additionally, some people consider the levels to be the literal peeks and
some insist it is based on a power curve or RMS average.
Dynamic range is normally expressed in decibels (dB).
The typical dynamic range for a cassette recording is around 60dB, analog
mastering tape without noise reduction about 76dB, CDs can reach a dynamic
range of just under 100dB. Compare this to 120dB or more for live orchestral
performances.
Although the term is thrown around loosely, I prefer the literal definition.
The difference between the loudest part of the recording and the softest
part. Expressed in db and representing literal peek levels. This is a simple
calculation using Wavelab.

I have a song and I want to see how much "range" it covers. Basically, how
compressed or dynamic it is. What do you recommend?

Thanks in advance.

So how do I measure the range that a song has. For example some pop songs
I'm watching don't appear to move more tha 8db on the Paris meters. Constant
volume with only 6 to 8db changing. How to quantify that?

I would use the statistics tools in either Wavelab or CEP to determine the
lowest level and the highest peak in dB, and subtract to get the difference
(easier than watching peak meters to see how far they drop - you have a peak
hold that will work for the highest peak level). With pop, rock, R&B, etc,
it really might only be 6 or 8dB.

That is what I would consider the dynamic range of a song - just the simple
difference between the highest peak and the lowest (including silent
sections). With a silent break in the song somewhere, the song's dynamic
range could actually be 80 or 90+dB.

Dedric

paris meters are not providing you an analysis of the audio but just
the peak value at any given moment in the song. they are not fast
enough to show all aspects of the sound you are monitoring.

Interesting. So what tools & functions are the best way to characterize a
songs dynamic range?

Take for example a song that has a very steady rock volume and I'm hearing
an isolated drum part of this driving beat and I'm trying to determine how
dynamic it is. Ideas? Using wavelab, harbal, cooledit, or a plug in?

How can I get the dynamic range for "program material". In other words,
I'm looking for the difference between the average loudest part compared
with the average quietest part over a 10 second period for example (think
of a verse of a rock and roll song). It's got a pretty consistent volume
but it does go up and down.

I'm basically trying to come up with a dynamic range that mirrors my favorite
songs in mastering and learning how much to compress on each instrument.

Thanks

For getting your mixes to sound competitive to other tracks in terms of loudness,
and compression, you should not be looking at dynamic range as much as RMS
Power (Also referred to as Average -power). The best method is to use a hardware
power meter like a Dorrough Electronics unit.

http://www.dorrough.com/Products/Digital_Audio_Meters/digita l_audio_meters.html

WaveLab Sound Forge and many other editors will give you this number, so
you can run your favorite tracks through and compare to your tracks.. Just
not in real-time like a meter.

A good video tutorial is on the Har-Bal site:

Voxengo Span is a free VST real-time spectrum analyzer that also
has RMS & Peak RMS readouts.

And it's free.

Did I mention it's free?

Good call on the Voxengo plug.
Interestingly, my Dorrough meter, Voxengo Span and Wavelab all give dramatically
different readings, but all three are helpful, as is InspectorXL.

john,

as a side note, if it's more of the occasional level variation you are
concerned with...why not just do level adjustments as if you were
flying the faders as opposed to using compression on every track?
myself, am more inclined to do the "gain change" on a passage then to
throw a compressor on to level things out...just a thought.

Sooooo.........if we all start acting like a bunch of compressors, isn't
that going to get us in trouble with the compressors union?

I keep thinking I need hard compression to get the drums in the pocket. They
are so dynamic currently. I'm just trying to tame drum tracks. Ideas?

What does RMS tell you about dynamics as opposed to just overall volume?

Peek levels have nothing to do with how loud a recording is perceived. A
record can have a very low overall level and have a few peeks that are never
even really heard. Technically this recording could have a very high dynamic
range and yet have all the audio recorded in a very narrow range of levels
with just a few added peeks. This is why simply looking for a specific dynamic
range won’t necessarily mean anything.

RMS is the closest measurement we have to perceived level. On radio its
called power. It’s a weighted average of the recorded level.

The waves paz looks interesting. I can put an EQ in front of it and isolate
frequencies and it appears to show the dynamic range of my kick. Lots to
learn.

so are you talking dynamics relative to specific frequencies of a
sound? selective equing can certainly alters ones perception of
"level" without actually making it any louder. this is the art of
making space for everything in the mix...knowing what to take out to
let the other in.

But also, if you're using Span, or something else that has
both RMS & PRMS readouts, you can get a gauge of the overall
dynamics by comparing the two readings. If you've got a PRMS
of -7, and an RMS of -20, there are more dynamics than if
you're PRMS is again -7, but your RMS is -12.
Obviously, these readouts are going to vary from one part of a
song to another (unless Vlado Meller mastered it :D ), but if
you're trying to compare your mix to a commercially-released
track & get similar dynamics out of yours, these two readings
can be helpful (as can your ears).

Yeah I think so. The Waves Paz seems to show me a nice difference in the
dynamics. I think that's what I need. Thanks guys.
