Microphone | lightweight framework to run self hosting REST services | Continuous Deployment library

After lots of trial and error I found a working solution. It's a bit strange, but I had to enable Flipper. I did not find a way without it.

Thanks to this answer: https://github.com/facebook/react-native/issues/31179#issuecomment-831932941 I found out about fixing Pods.

This is my Podfile now:

You're missing some command line flags that tell chrome to simulate having a microphone. Give this sample a shot.

I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.

Yes! 🎉 However, it only works if the audio session is created with the allowBluetoothA2DP option (according to @RobNapier above). It is an output-only profile, therefore it does not route input from the Bluetooth devices at all.

A2DP is a stereo, output-only profile intended for higher bandwidth audio use cases, such as music playback. The system automatically routes to A2DP ports if you configure an app’s audio session to use the ambient, soloAmbient, or playback categories.

Starting with iOS 10.0, apps using the playAndRecord category may also allow routing output to paired Bluetooth A2DP devices. To enable this behavior, pass this category option when setting your audio session’s category.

You can make it work with a bare-bones sound manager something like below.

In golang I have taken an array ARR1 which represents a time series ( could be audio or in my case an image ) where each element of this time domain array is a floating point value which represents the height of the raw audio curve as it wobbles ... I then fed this floating point array into a FFT call which returned a new array ARR2 by definition in the frequency domain where each element of this array is a single complex number where both the real and the imaginary parts are floating points ... when I then fed this array into an inverse FFT call ( IFFT ) it gave back a floating point array ARR3 in the time domain ... to a first approximation ARR3 matched ARR1 ... needless to say if I then took ARR3 and fed it into a FFT call its output ARR4 would match ARR2 ... essentially you have this time_domain_array --> FFT call -> frequency_domain_array --> InverseFFT call -> time_domain_array ... rinse N repeat

I know Web Audio API has a FFT call ... do not know whether it has an IFFT api call however if no IFFT ( inverse FFT ) you can write your own such function here is how ... iterate across ARR2 and for each element calculate the magnitude of this frequency ( each element of ARR2 represents one frequency and in the literature you will see ARR2 referred to as the frequency bins which simply means each element of the array holds one complex number and as you iterate across the array each successive element represents a distinct frequency starting from element 0 to store frequency 0 and each subsequent array element will represent a frequency defined by adding incr_freq to the frequency of the prior array element )

Each index of ARR2 represents a frequency where element 0 is the DC bias which is the zero offset bias of your input ARR1 curve if its centered about the zero crossing point this value is zero normally element 0 can be ignored ... the difference in frequency between each element of ARR2 is a constant frequency increment which can be calculated using

The permission_handler package introduced a breaking change in version 8.0.0, see changelog. Permissions on iOS are disabled by default, and you have the set the correct GCC_PREPROCESSOR_DEFINITIONS in you Podfile. An example Podfile can be found here, but basically you have to add this to you Podfile, set the permissions that you don't use to 0:

Seems like probably you have a mistake in you DTS file. Given its I2S input you should use these 3 pins:

It seems to have been removed in version 9, but the documentation has not been updated. You can use openRecorder() instead or switch to an older version of the library.
