I am working with audio analysis and am having some trouble getting

I want to analyse an audio signal and have an output similar to a

spectroscope (not spectrogram!) where the amplitude of the various

frequencies in a signal are displayed in a traditional x=frequency

y=amplitude and can be used as control for various other processes.

The spectroscope in max uses 30-40% of my cpu when there is a full

frequency signal going into it and I cannot seem to access the

individual frequency bands for use as control. I have read the

analysis tutorials and I can't penetrate them. They seem to be all

It says right at the beginning: "fft~ receives a signal in its inlet.

For each slice of time it receives (512 samples long by default) it

sends out a signal of the same length listing the amount of energy in

each frequency region." Why can't I access this information? I feel

like I am missing something fundamental. I don't even need 512 bands.

10 would be okay, 64 would be better, 128 would be good.

I have a spectroscpe in my recording software only using 2% of my cpu

so I know it is possible to do I just can't figure out how to do it in

I am working with audio analysis and am having some trouble getting
the information I need.

I want to analyse an audio signal and have an output similar to a
spectroscope (not spectrogram!) where the amplitude of the various
frequencies in a signal are displayed in a traditional x=frequency
y=amplitude and can be used as control for various other processes.

The spectroscope in max uses 30-40% of my cpu when there is a full
frequency signal going into it and I cannot seem to access the
individual frequency bands for use as control.  I have read the
analysis tutorials and I can't penetrate them.  They seem to be all
aimed towards processing.

It says right at the beginning: "fft~ receives a signal in its inlet.
For each slice of time it receives (512 samples long by default) it
sends out a signal of the same length listing the amount of energy in
each frequency region." Why can't I access this information?  I feel
like I am missing something fundamental.  I don't even need 512 bands.
 10 would be okay, 64 would be better, 128 would be good.

I have a spectroscpe in my recording software only using 2% of my cpu
so I know it is possible to do I just can't figure out how to do it in
max.

This might not be the best advice, but thought it worth posting:

Have you looked at Miller puckette's fiddle~ object and also analyzer~ by Tristan Jehan?

They have bins with spectral analysis so perhaps you could build a low power spectroscope from them?

Also, Gabor objects from IRCAM might be useful.

I don't have any CPU issues with spectroscope - I see hardly any impact

at all on load when I include one in a patch. You might try

experimenting with different signal vector sizes in your DSP settings.

That said, it seems what you are really after is not so much

visualization as the ability to follow the amplitude data in particular

I don't have any CPU issues with spectroscope - I see hardly any impact
at all on load when I include one in a patch.  You might try
experimenting with different signal vector sizes in your DSP settings.

That said, it seems what you are really after is not so much
visualization as the ability to follow the amplitude data in particular
FFT bins.  Here is one way to do that...

Yes, I found what I was looking for in fiddle~ which until recently I

I couldn't get your patch to open either. Are you on mac and what version?

And I just noticed that you have a uoft address! We should meet

sometime as I have recently moved to Toronto and am looking to get

Yes, I found what I was looking for in fiddle~ which until recently I
couldn't get to work on my xp machine.

I couldn't get your patch to open either.  Are you on mac and what version?

And I just noticed that you have a uoft address!  We should meet
sometime as I have recently moved to Toronto and am looking to get
involved here.

Maybe fft is overkill, the analyzer below is based on fffb~, you can 

The big advantage is the logarithmic output...
