QUESTION
I am trying to record audio and process it afterwards. As I understand there is no unified API I could use to access microphone across different platforms. I am aiming at WASM, UWP and Android.
My approach is to record audio with platform-specific code.
For UWP I can use MediaCapture class as described here: link. I have implemented this part and it's working just fine.
For Android it should be straight forward as well. I can use Android.Media.MediaRecorder as shown here: link. I am not sure how to get the recorded audio file afterwards.
As for WASM I am completely lost here. I suppose I could use some javascript library to record the sound or vmsg library as described here link. But I have no idea how to get the recorded data into C# code for further processing.
Is there some material I should read to better understand the topic. Do I overlook some important details? Or is there an easy way how to record audio in xamarin.android and wasm?
UPDATE: I have successfully implemented audio capture on Android using Android.Media.MediaRecorder and I can simply access the file after I am finished recording.

Answered 2021-May-16 at 08:38I finally have the recording working on all three platforms (UWP, Android, WASM). The goal here is to obtain raw PCM audio data with a 48 kHz sample rate, 1 channel and 16 bits per sample.

QUESTION
I have been looking to cut a audio blob in Js, and return a cut blob.
The blob is registered using WebAudioRecorder.js and using the mic of your pc.
I already found this repo: mp3-cutter, but it is written in node.js, and require to have access to the filesystem.
I also found this one: audio-cutter, but it has a UI.
I have explored multiple solution and did not find any simple solution.
While analyzing the recording, i found out that the mp3 registered with the mic have a 1024 bit header. Using this, and based on this, i wrote little Js function:
...ANSWER
Answered 2020-Sep-18 at 12:41Okay, i found out.
You need to convert your blob to ArrayBuffer, then to AudioBuffer, cut it, then reencode it using a encoder like mp3-lame-encoder-js
To help, i wrote a little library called simple-mp3-cutter
QUESTION
I use audio-recorder-polyfill in my React project, to make possible audio recording for Safari. It seems to work in getting the recording to take place, however, no audio data gets available. The event "dataavailable" never gets fired, and no data seems to be "compiled" after stopping recording either.
...ANSWER
Answered 2020-Apr-15 at 16:43There have been a number of similar issues posted on audio-recorder-polyfill's issue tracker. a b c d e
Root causeOne of those issues, #4 (not listed above), is still open. Several comments on that issue tracker hint that the root issue is that Safari cancels the AudioContext
if it was not created in a handler for a user interaction (e.g. a click).
You may be able to get it to work if you:
- Do the initialisation inside a handler for user interaction (i.e.
)
- Do not attempt to reuse the
MediaStream
returned fromgetUserMedia()
for multiple recordings - Do not attempt more than 4 (or 6?) audio recordings on the same page (sources [1], [2] mention that Safari will block this)
You might also be able to try the StereoAudioRecorder
class from the RecordRTC package, which has more users (3K) but appears less maintained, and might work
If you'd prefer to stick to the MediaRecorder API and the tips above don't work for you, the good news is that there is experimental support for MediaRecorder in Safari 12.4 and up (iOS and macOS), and it appears to be supported in the latest Safari Technology Preview.

QUESTION
I am working on a Cordova based project based on Android, and I am trying to know what is the minimum version supported by the Android platform.

ANSWER
Answered 2019-Jun-05 at 14:57You're doing this backwards. You don't write an app then figure out the minimum version. You pick the minimum version you want to support, based on marketshare and demographics of the different versions, and the effort it would take to support lower versions, and if there's any must have functionality that requires a specific version. Then you pick only plugins that work for that version. You don't create an app then try and figure out a minimum version- doing it that way you have no idea if it supports the market you're aiming for.
