Hello dear members,
My task is almost finished, I have an algorithm that reproduce the sound of a motor. But it seems the process is locking a part of the electronics inside the teensy.
In fact I...

Nianiania ! 96%of RAM!

I corrected this bug in the previous code.

Thanks, I keep Learning!

In term of optimisation, I can put audioMemory(5). i Don't know how the result change, do You?

I need to explain why I want to use pulseIn: it is for a RC truck, my...

I m not sure increasing audio memory will solve the problem

There is still something wrong, I'd like to put a function "pulseIn()" but there is a conflict with "AudioMemory(15)"
In fact, when pulsein() is called without audioMemory my fonction works fine,...

Hello,
With some usefull tips, I made the sound of a motor. The engine go from 500RPM to 4000RPM.
Here is the diagram made with pjrc audio library. if you want to hear the sound you need a...

Now i think it's better, still missing the exhaust pipe and we done!



#include <Audio.h>
#include <Wire.h>
#include <SPI.h>

I put a multiply block between the sound created by the cylinders/blasts and a sine. The result is much better at low speed, I'm happy! Nevertheless the whole lack of realism at high speed. Did I...

Hello
I made several changes to the code:
- A PID regulator for throttle control
- The noise is simulated by the envelope function, interesting!
- Added a random function...

maybe strings tool???

The following point is still a mystery for me:

I understand the sentence but not how to achieve it, could explain me this further?

I found accidentally a method to simulate the sound of the engine start-up.



#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
int R=0;
long t0=0;
// GUItool: begin automatically...

Hello
Here's the GremlinWrangler program test. I changed some settings and I find the result very good. Now, to improve this code, I will add a more explosive "bang", simulating the explosion of...

That's pretty good, freverbs add some realistic to the sound, i keep trying with différents parameters. when the code is okay i'll publish it

Okay, I can see more clearly. I'm doing tests today. I'll send you a code tonight.
And thanks to you GreemlinWrangler for your code, i'll try it now

Hello
Thanks for your reply, nevertheless I am a little lost by the techniques you use. In the first step you talk about Dirac and equations which I have no idea of their content.
The second...

Hello,
I can't find the function that accelerates the playback speed of a WAV sound. Could someone help me please ?

Ok Beware the dog ;) I understand the way it mean, lot of sound.wav or Sd??

I ve put the wav file into my sd card, if I change the format into *.mp3, do I have the same results? then i may ask if...

Kind of mixer?

While doing research, I realized that an engine was not only a sound but a set of distinct sounds as clutches, valves ... and for the V8, it emits a very special explosion sound. Would you know where...

Dear members of the forum,
I just received my Teensy 3.2 with the audio shield. I soldered everything, and then did the first tests with the Arduino IDE samples. What a joy to see that everything...

Salutation to the Community of this forum!
I noticed that few years ago, somebody called Paul Stoffregen, rised enough money to create the teensy project. He used a crowfounding site untitled...

The speakers I mean have an usb connection and jack.
their usb connection are peripherals as sayed Davidelvig so they only work linked with computers or a tab.
I can intend to make a loopback...

Ok, I've read the paper.
I tried to make the DAC option. That work fine. Something to know is that output have an DC offset- it's written on the GUI audio interface- an 10µF capacitor is...

hello,
I wonder what happened if i connect a speaker to a Teensy set with audio setting from the arduino IDE?
Thank you :)
