sd card problem

[gorkem]

ı use teensy audio board for audio processing. ı cant take clear informations . occurs so much noise while playing music. what is the problem ? is it related to breadboard?

I would suggest working through each part of your project and testing one at a time.

can you use the SD card examples alone to read data to from the computer?
can you use the synth examples to play a tone?
can you play a known good test file from the SD card?

The wiring will not be helping, but assuming you are using the headset out there is only digital data on those wires.

ı tested my sd card with sdcardtest program in library . it is not broken. and ı tried to play a sound from library (part_1_Playing_Music) there are so much noise at the sound. the sounds are not healthy. can it be related to quality of sd card ? also ı tryed to use deelay program in library. ı couldnt get any sound by microphone. there is only a bip sound.

It's possible that SD card quality can cause sound problems but normally only play high quality/data rate files.

More likely is problems around the setup of the board. What do you get if you load the tonesweep example under audio->hardwareTesting?

If you need to test a microphone suggest the peaklevel example under analysis.

Also confirm you are listening on a pair of headphones plugged into the headphone jack?
