implement the feature to produce the waves using phone audio jack
Actual Behaviour
Currently their is no such functionality available to produce different from audio jack of phone
Expected Behaviour
It is an additional functionality, in this, the audio jack of the phone can be used to produce different waves like sine, square, triangular which can be analyzed in the oscilloscope.
Steps to reproduce it
Wave generator -> Implement the functionality using AudioTrack class provided by android
Would you like to work on the issue?
Yes
@Avjeet It would be great if you first focus on the digital waves generator pins as it's difficult for me to everytime use Control Activity for testing and then remove the changes before commit. No digital pins i.e. SQR1, SQR2, SQR3, and SQR4 are working correctly.
I would like to work on this. Reference :- https://blog.fossasia.org/filling-audio-buffer-to-generate-waves-in-the-pslab-android-app/ @CloudyPadmal
@neel1998 @CloudyPadmal @mariobehling I don't think this is any different from the in-built mic functionality that we have already as we are using AudioJack instance for that functionality as well. This can be closed.
This is about producing waves; not observing. Do we have that feature?
I didn't understand your point. Currently we are displaying the wave produced by the sound on the oscilloscope. What do you mean by producing...??
Can you read and understand the title of this issue? You can also read the issue body if it's still hard for you to understand.
@CloudyPadmal here is what i have understood, the user will decide some wave let's say some sine/triangular wave with freq,amp and phase, and we are suppose to produce a sound wave based on that. For example, whistling is a kind of a sine wave, so if user gives sine wave to this feature, a sound like whistle should be produced. Am i correct?
