thanks,
i will ask there too

Thanks

but how to accomplish this:

there is no documentation or something
do i habe to write it in the store in the app description?
Do you know any example-text?

Thanks

Hi,
how can i publish an app which uses libpd?
What about the license?

Thanks

Hi,

i have one wav-File in an array which i read with 16 [tabread4~]
at different speed for 16 different pitches of the sound.

i could have one or up to 16 "pitchplayer" run simultaneously,
how can i control the gain?

i'm trying this:
before a tabread4~ starts it increases a number, when its's finished
(a delay with the delaytime=time of the [line] which feeds tabread4~)
it decreases the number
the overall output (before dac~) is divided by this number

this is not working good, the sound "crackles" when the number decreases

how is this, i think basic task, done?
how can i achieve a constant gain? (without dividing the output by 16 statically, which results in low gain when playing only 1 or few pitches at the same time)

Thanks
Frank

Hi,

ist it possible to have a timer or counter etc. with a higher resolution than 1ms in vanilla?

thanks

Hi,

I am totally new to pure data.

I'm looking for a patch to record something (hit on a drum or glass etc.) for about 1 sec and then check the main frequency of that recording.

The fiddle object can only compute frequencies down to 53 hz, right?
But i need down to 20-30 hz.
And real time is not needed, so i think first record 1 sec and right after that
compute the frequency would be right.

How can this be achieved?

Thanks,

Frank

great, thanks

yes, there you can see that the decimals are dropped
so e.g. 133bpm would be 451ms instead of 451.278... ms
but maybe this is too theoretical

thanks,
i's like to have a bpm metro but with 1ms it is (theoretical) not correct
e.g. 133bpm = 451.278..... ms

also i's like to start readsf~ on a time based on bpm
so del takes floats? great

hi,
sorry for that late post, i was busy with other things and thanks for your answers.

I decided to first do it in java as I'm new to dsp and new to pure data but not so new to java.
So this is not really a pure data related question but a dsp related one, i hope you don't mind.

I focused on getting the fundamental frequency of a drum:
I record 65536 samples at 44100 hz and than do a fft with these samples.
When i plot the range from 0-1000hz (~the range of interest for drums),
i get 3-5 frequency-peaks. For human eyes it is simple to see the first (lowest frequency) peak, which would be the fundamental frequency.
But the first is not always the loudest , so i can't iterate over the fft output to find the bin with the strongest power.
So how do i get the first peak programmatically?
Or the 3-5 peaks mentioned above, so i could take the one with lowest frequency.
As said, the peaks are clear peaks, for eyes no problem to see the first (fundamental).
As the peaks a really clear it shouldn't be so difficult to get them---but how?
The question is, what is a peak in programmatic expression.
What does the human eye do when looking at the plot?

I hope someone could explain me in easy steps what to do with the fft output

Thanks very much

Thanks Maelstorm,

but as i know, Timpanies e.g. are really tuned

and that some drummers tune there drums in e.g. 5 semitones difference (toms)

or the bassdrum to the key of a song.

Maybe i shouldn't just use the ready-to-use object fiddle, but build a patch with rfft?

As i said I'm new to puredata and also new to dsp so i need a startingpoint.

I'm going to use libpd later on, so i could add some computations or controlling,
if necessary, once i got the spectral analyzing (right word?) and of course the knowhow;)

So this would be the steps:

• record 1 sec
• do the fft (real or complex??---totally new to dsp...)
• look at the data and find the fundamental (in the "host" of libpd, if needed, better in pure data itself)

Thanks for your answer,

i'll look at sigmund~

But isn't there something like a main frequency in percussion and in general in all "objects"?
