I am iOS developer . I have wav file and I am sending this url to pd file and I want that pd file run this audio file.

"/Users/erhandemirci/Library/Containers/CFFBC752-68DE-4B98-B570-6E0E973C3403/Data/Documents/outputAudio.wav"

my swift code :
[PdBase sendSymbol: wavpath toReceiver:@"setAudioFilePath"];

#X obj 69 136 s setAudioFilePath; # setAudioFilePath receiver

my pd files is not correct . can you help me please . outputAudio.wav
mypdFile.pd

@erhandemirci The [delwrite~] that you copied was in an abstraction....... a patch acting like a subroutine.
The $1 would have taken its value from the first argument of that abstraction.
So here it has no value.
[delwrite~] needs to be [delwrite~ name length-in-milliseconds] so say [delwrite~ mydelay 10000] which will write to memory a buffer of 10 seconds.
[delread~] needs the same name and you can set the point at which it reads with the 3rd argument within.
So [delread~ mydelay 5000] will read from the buffer at 5 seconds.
You can send a mumber that will replace that 3rd argument into the left inlet of [delread~]

A $0 in an object name makes it unique.... it is not a global variable... It takes a value that is assigned as a patch window is created (1st patch opened... 1001... second 1002 etc.), and any sub-patch within the patch has the same value for $0.
Useful for isolating sends and receives etc. from other patches that might be open..... or even from the same patch opened twice.

thanks David @whale-av . Awesome. eechocompleted.pd we solved the echo with your advice. Only the pitch remained.
sorry for too many questions. How can I add pitch ?
Thank you .

@erhandemirci Maybe...... added before echo....... so-far.pd
David.

Thank you David @whale-av . I used so-far.pd as a result of echo and pinch myWork.mp3 my voice became like this. But I want it to be like this resultMustBe.mp3 .
What I need for that ? thank you .

original sound : orjinalSound.wav

@erhandemirci This gives you options for fine tuning by ear.... so-far-2.pd
When you save the patch it will save the values of the sliders.
Maybe the pitch/total time relationship can be calculated, but that depends on why the original seems slow.
David.

@whale-av Thank you so much David. Awesome .

I had the audio analyzed in chatgpt and it said we needed to add these to the original audio. I added them but couldn't produce any results.

1. Convert Mono to Stereo
   Steps:
   Use [adc~] to capture the input signal.
   Create two outputs with [dac~ 1 2] to output audio to stereo channels.
   Use [*~] and [phasor~] objects to add slight differences in the left and right channels for stereo enhancement.
2. Adjust Pitch or Time
   Pitch Shift:
   Use [phasor~] as a base waveform.
   Process the audio through a pitch-shifting module using [tabread4~] or granular synthesis techniques.
   Optionally, add a [vslider] or [hslider] to control pitch.
   Time Compression:
   Implement a simple time-stretching algorithm with [delwrite~] and [delread4~].
   Adjust delay times to compress the duration.
3. Apply Equalization
   Steps:
   Use [biquad~] to build a parametric equalizer.
   Boost specific frequencies:
   High frequencies: Use [hip~] or [biquad~] with a high-pass filter configuration.
   Mids: Add a peak filter in [biquad~].
   Low frequencies: Use [lop~] to attenuate the bass.
   Chain filters as needed to create a full EQ.
4. Add Reverb
   Steps:
   Use [freeverb~] (available in many Pd libraries) for a basic reverb effect.
   Adjust room size, damping, and wet/dry mix for subtle ambiance.
   Alternatively, build a custom reverb with [delwrite~], [delread4~], and feedback loops.
5. Stereo Effects (Optional)
   Chorus/Delay:
   Use [delwrite~] and [delread4~] with slightly modulated delay times for a chorus effect.
   Add LFO modulation with [osc~] to vary the delay time periodically.

if possible to can you help please
Thank you @whale-av David

@erhandemirci Post your patch and I will look at why you were not successful.
Also have a look at Automatonism..... https://www.automatonism.com/

Follow the instructions carefully........ as you add modules they and their settings are saved within main.pd.
Make a copy of the original download, and use that if you want to start again or start a new patch.

There are modules for most of what you will need I think.

new-play-any.pd

I mixed a lot and made many files. I couldn't find it now, but we can proceed through this pd file. new-play-any.pd . I want to do the steps on this pd. I apologize, I had a hard time with this.

I would like to add reverb but I can't hear any sound

play-reverb.pd
@whale-av

I read your answer in this [post ] (https://forum.pdpatchrepo.info/topic/5349/patching-a-good-reverb/11) but I can't apply

@erhandemirci It is very likely that some of the objects inside the object [reverb282~] do not exist in your installation.
Missing objects will not create and will appear with a dotted line around them instead of a box.
Here are those that were included by the author..... R282.zip

But there will be others missing because the object was built using an old version of Pd.... Pd Extended.
It was 32bit and Pd Vanilla is now 64bit.
So you will need to find the missing objects hoping that they will have been re-compiled for 64-bit.

You can do that by going to the Pd top menu...... Help... Find Externals and looking for them in the search window and then installing the library that appears for your os.
One that will probably be missing is [lp8_cheb~] which is available through that method (it is actually an abstraction but with luck any externals necessary should be included in the library that will be installed).

There might be many missing, and they will be listed in the console, but interspersed with all the other messages. You will need to scroll up the console looking for red ink.

But others might never have been recompiled.

If you are unlucky then try using one of the new reverbs...... [rev1~] [rev2~] rev3~]
David.

thank you David @whale-av

I can hear sound from this PD file in Swift using new-play-any After applying the following steps:

Mono to Stereo,
Adjust Pitch,
Apply Equalization,
Add Reverb,
I created a new PD file named EqAndReverbAndPhasorAddedAndEcho.pd . However, I can't hear any sound from this new PD file in Swift.

Can you help me figure out what I did wrong?
Thanks!

@erhandemirci this.pd
David.

@whale-av thank you. But now there is sound but no sound effects are added

@erhandemirci No idea..... it works for me..... reverb and echo.......
I could not tell whether the EQ was working so I have added [lowpass] controls for the [biquad~]....... and [highpass] and [notch] and others which you could patch into [biquad~] if you wish.

A new.......this.pd

Check for errors in the console in case something is missing.
David.

I can hear sound effects on Pd-0.55-2 but I can't hear sound effects on my swift code .
new-this.pd

[PdBase sendFloat:26 toReceiver:@"revValue"];
I read from swift revValue and send to parameter >>> 16

maybe I need to send another value ? or I have another problem

@erhandemirci Sorry, I know nothing at all about Swift.
After a quick search on the internet it seems that no externals can be used with swift..... so only objects contained within a basic install of Pd (vanilla) will work.

The only objects I can see that will not work are the filter externals...... [lowpass] etc.
That means unfortunately that you will need to calculate the parameters for [biquad~]
David.

Hello, I couldn't do this, it's a pure data file that reads the wav file and only does the "reverb effect"

I have a request from you, if you have the chance to create it, can you share with me pd file ?
thank you. @whale-av
