How to capture and send audio to another interface (Visual Basic or Delphi)

by luiz_antoniosp on Wed Aug 07, 2013 5:36 pm

Hello,

I Do 2 control line through the Arduino telephonic Duelamilanove
Using ports Digital Audio However these online'm sending to
recording the microphone input of the sound card of the PC.

I would send these two channels of audio (8bit Mono Each)
the analog ports of the Arduino, sending these audio data for some
place the computer where I can capture this audio buffer
through my interface and then do the Recording file individually
each telephone line.

Hi. I' have moved this topic to a more appropriate forum.

From your post, it is not clear what Adafruit products you are using. Please provide more detail about what you are trying to accomplish.

Watch this video

the audio comes through the microphone input of the computer
however I want the audio from this:

ANALOG_ARDUINO> USB> SERIAL> MY inteface

What I want to know is:

* How can I capture audio data that travels in arduino and send
for an interface in Delphi.

* How do I intend to send two signal lines telefonica want to know

* How to do this since I have two audio line
  8bits each and arduino only have 10bits:

The solution would be to use this:

However I do not know how to do;

The ADS 1115 is a high-resolution device. However the maximum sample rate is 860 Hz, so it is not suitable for audio.

USB/Serial is also not well suited for audio transfer. The maximum data rate is about 11KHz, but with only 8-bit resolution. That is relatively low-quality audio. The bigger problem would be the latency and jitter inherent in the USB/Serial data transfer. Good quality audio is possible over USB using the isochronous transfer mode. But that is not a capability native to the Arduino.
