1  Using Arduino / Audio / Re: Hi need help, suggest me a preamp circuit for realtime audio processing. on: April 12, 2013, 01:32:36 am
Thanks DVDdoug,

i have found a circuit preamp for TL082, this one? .

do you think this is work?


2  Using Arduino / Audio / Hi need help, suggest me a preamp circuit for realtime audio processing. on: April 11, 2013, 11:45:06 pm
Hello guys,

I am looking for the best preamp for guitar using TL082 or lm358. i saw a link http://audio.circuitlab.org/2012/06/simple-preamp-mic-using-lm358.html. but i never try this. what i have now is TL082 IC to make the preamp for guitar.  i want to use this sketch for a while.http://interface.khm.de/index.php/lab/experiments/arduino-realtime-audio-processing/

any recommendation?

Thanks in advance!

This is nice sketch.. http://wiki.openmusiclabs.com/wiki/PWMDAC smiley but how could i do the circuit for guitar signal?

Hi DVDdoug,

I try what you suggested, changing the 100 to 2meg and also changing the 10k pot to 100k pot. but it does'nt output any guitar sound on 8ohm speaker, anyway is it working on 8ohm speaker?


thanks in advance! smiley
5  Using Arduino / Audio / Hi Guys, I need some guide on audio =) on: March 27, 2013, 07:26:18 am
hello guys,

thank you so much for viewing on my post. Ok i just having a simple question. i found this blog and it is very very http://interface.khm.de/index.php/lab/experiments/arduino-realtime-audio-processing/ to begin with custom guitar pedal. i am trying to make a tweak on the circuit. to be usefull in guitar amplifier, however i still remain failed to do it and i want to keep trying.=)  i'm using "LM324" and trying to search a good circuit for it. but i still failed to do it and know i am in "LM386" the problem on it have a very noisy sounds. i know that i have a limitation on circuit but i willing to learn and spend time working on it. =)

can anyone suggest me a circuit for guitar pedal that works on amp or speaker with the use of any of this LM324 or LM386? =)

Thank you so so much and very very much for any answer!=)


Regards

6  Using Arduino / Audio / is there other software for midi controller but not ableton or garageband? on: October 23, 2012, 10:25:32 am
is there other software for midi controller but not ableton or garageband? i am working on this http://spikenzielabs.com/SpikenzieLabs/Serial_MIDI.html which are to convert serial to midi. and work with ableton and garageband, but i need other free software that deals with midi drums.

is there any suggestion software or options??

8  Using Arduino / Audio / How i can store 1 second audio using eeprom and read it. on: October 10, 2012, 03:52:34 am
Hi Guys,
How i can store 1 second audio using eeprom and read it. I have a 1 second audio mp3 and i want to store it to eeprom and read it, how can i code it?

9  Using Arduino / Audio / Re: Guide Me how i can write and read audio simple on arduino EEPROM on: October 09, 2012, 12:20:38 pm
Thanks for all Reponses, and i really understand it. but i want to now how actually code it? Maybe something like:
    val = analogRead(0);
     eemprom.write(address, val);?

   maybe  PWM is equal to eemprom.read(address)?



10  Using Arduino / Audio / Re: Guide Me how i can write and read audio simple on arduino EEPROM on: October 09, 2012, 11:52:51 am
Yes, How about it is just a few second? 
11  Using Arduino / Audio / Guide Me how i can write and read audio simple on arduino EEPROM on: October 09, 2012, 11:30:59 am
Guide me on how i can write and read audio,  in arduino EEPROM. Maybe Just a second,  for just an example how to start.?  smiley

Anyone?

Hi Guys, Thank you, I appreciated for those answer,I am taking the experiment of "overclocking"  and let see. smiley-wink  i will be back, please put more suggestion here.

Hi Thanks for quick response.  so is there other way to speed the clock speed of atmega328?
14  Using Arduino / Programming Questions / How to enable the External Occillation. on: October 07, 2012, 09:44:28 am
Hello Guys,
I am confused if, atmega328  run around 100mhz with the external crystal Oscillator. is it possible? if is it possible How to enable the External Oscillation in Arduino Register and used external crystal oscillator ?


Thanks
15  Using Arduino / Audio / Make a Preamp with 2N9304 Transistor/Arduino on: September 03, 2012, 12:13:48 am
Hello Guys,


I have wonder How i can build 1 Preamp using 2N9304 Transistor. and the output should be connected to the Analogs Pin. I am  trying to  very basic guitar effects. But i dont know how to build preamp.  smiley-roll-sweat



Dsese.
