audiorecorder | cross platform javascript utility | Audio Utils library

Please help me! I want to record small size voice files in Android using Titanium.

I am using Titanium.Media.AudioRecorder() to record voice files, but the size of the generated files are too large.

I would like to generate small size voice files. It doesn't matter to have low quality.

What format and what compression type should I use to get better results (small size files)? Thank you

I am using the code below:

Okay, so I've been trying to do this for a long time but I just can't find a solution. I'm building a personal Voice Assistant that only records when a hotword is detected, and everything until here works fine. To record the audio, I'm using the npm package node-record-lcpm16. I can't seem to find a solution to pause or stop(and start again) the recording. On the npm website of the audiorecorder there is a function specified that says recording.stop() but it doesn't work for me. My code right now is:

I'm acquiring PCM raw bytes with new AudioContext({ sampleRate: 16000 }) (note, I'm using Chrome, which supports the sampleRate option), and I'd like to convert the resulting array into a DataView object.

My current code is the following, in the stop method I read the left channel and store it as an array of Float32Arrays.

For the web app I'm building in React, I need to record audio and be able to somehow put that recorded audio in the app's global state so I can use and manipulate that recorded audio in different components of the app.

My global state is setup using React Hooks (made and managed with useReducer, createContext, useContext) and I believe Hooks only work for functional components, not class components.

So the issue I'm running up against is that every tutorial I've followed to get my browser microphone to work uses class components (like the code below), not functional components. And I'm assuming that this is for good reason because when I've tried to translate these class components into functional components, I get the error: "cannot read property 'finish' of 'undefined'"

Are there ways to take this audio data (blobURL) and pass it to my global state?

Alternatively (and ideally), is there a way to use the microphone to record audio in a functional component instead of a class component?

I am trying to return the current decibel level from the iPhone's microphone. I have pieced together this code below and cannot figure out why it won't work. My expectation is that for now it will print the current peak power continuously to the console.

So my questions/issues are:

1. Will "peakPowerForchannel" return the current level or the max for the entire audio session?
2. It appears my button never turns to the stop recording mode and just prints "recording started" every time it is pressed.
3. I can't figure out why the decibel level won't print at all.

Thanks for the help!

I'm working on an app that does audio recording and playback of recorded audio. I'm using AVAudioSession to change the category to playAndRecord as well as passing it to defaultToSpeaker.

My problem is, if I launch the app, play an earlier recording, it plays through the bottom (louder) speaker as I want it to and expected BUT if I launch the app and start recording a new memo then play it back, no matter what I do, it will always use the quieter (phone call) speaker that's next to front face camera. I need it to play from the louder speaker (actually all speakers if possible).

NOTE: I'm running iOS 14.2.1, my phone is set to silent mode (usually) though I tried other settings as well. I'm testing on an iPhone 12. Ideally, I'm not really looking for a 3rd party SDK or library solution as I want the playback to be simple and done natively.

This is how I set the audioSession in my viewModel (that's initialized from a viewController):

I have this codes to get access token which should pass from signin screen -> navscreen -> homescreen-> griddashboard->forms ->add new post and send the post request to server with the token

Here is how I get the token

I am trying to build my own Recorder/Player using React-native-audio-toolkit.

Following their documentation but I am not sure how to prepare the record properly.

(on iOS simulator)

Here's my code
