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 Yes, that is not a valid Pd file.
This might help...... if you only want to play the file then [readsf~] is more friendly.
cart-mod.pd

Otherwise, if you intend to modify or manipulate the [array] then you need [soundfiler] to populate the array.

You can delete much of the attached file for your purpose.... stop... loop... etc. if you wish.
David.

EDIT.. I have just re-uploaded the file. The incoming message needs to be tagged as a symbol for $1 in the [open $1( message to process the message correctly.

thank you @whale-av . it's work . you saved my time . thank you . how can play audio at natural speed and tone ?My main goal Actually I want to add effect of echo and pitch to accomply the effects .

@erhandemirci To vary playback speed (rather then pitch shift - constant lemgth) you will need to write the file to an array.

For pitch shifting have a look at G09.pitchshift.pd in your Pd folder... pd/doc/3.audio.examples.
Inside the file (on the right) is an object [pd test-loop] and inside that you will find [soundfiler] writing a wav file to the array.
If you want the file to only play once the use [line~] instead of [phasor~] in that window.
You can play the file at different speed by varying the number sent into the left inlet of [phasor].

Right clicking and selecting help will give you the info you need for usage of an object.

You will find other effects in that folder, such as delay, echo reverb etc.

Can you please create a pd file for this?

I created this one but not success
mypdFile.pd

@erhandemirci The file I posted above will play at natural speed and tone.... but....
... the sample-rate that Pd is running (Pd top menu - Media - Audio Settings...) must be the same as the sample rate of the wav file.
An automatic correction can be applied when using [soundfiler] but not using [readsf~]

This will correct for sample rate......... play-any- sample- rate.pd
Again... some of it you will not need.
It uses [vline~] which is a more accurate version of [line~]
It will play just once (not cylcle as it would using [phasor~]

If you want it to cycle then [phasor~] will be easier to use for that, and the maths will be similar.

I agree with @whale-av, but if your latest issue is that there is no sound at all, then it's probably because you are muting it:

That audio multiplication is equivalent to multiplication by 0 because you have not provided a non-zero input to the right inlet. You can also just add a non-zero argument.

@whale-av @jameslo I wrote a Mac application and the sound does not sound natural there either. It is different, fast and incomprehensible. cart-mod.pd did the job but there is only this problem. I still couldn't solve it and I couldn't understand it because I am an iOS developer. I created new one and better but sound nearly understandable and nearly natural mypdFile.pd

@erhandemirci OK, I see another issue: your wav file is 22.05kHz 32 bits. I think that makes things more complicated, e.g. your sound card has to support it too, or you have to resample it in Pd. Try converting your sound to 44.1khz 16 bits.

@erhandemirci "play-any-sample-rate.pd" that I posted above will play a 11025Hz file at 16 bits without problems so I would expect 22050Hz to be fine. I don't think bit depth should be a problem.
As @jameslo says a conversion might solve the problem,..... BUT.... playing your file in vlc in Windows it has some distortion towards the end.
Not sure what IEEE codec is.... I will look it up.
David.
In case others know....
But I will try making a 22050/32 file to see what happens...

@erhandemirci But... VERY strangely...... no distortion in Pd.
Try this...... new-play-any.pd
David.

@whale-av thank you. Awesome . it's work . now playing sound natural.

Now I wanted to add echo, I think I did it right

echoTry.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.
David.

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.
David
