You can use the pydub library (a light wrapper I wrote around the python wave module in the std lib) to do it pretty simply: from pydub import AudioSegment sound1 = AudioSegment.from_file(“/path/to/my_sound.wav”) sound2 = AudioSegment.from_file(“/path/to/another_sound.wav”) combined = sound1.overlay(sound2) combined.export(“/path/to/combined.wav”, format=”wav”)
This won’t create a bring up the MediaPlayer interface… it will just play the sound you want. Button boton = (Button) findViewById(R.id.boton); boton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { MediaPlayer mp = MediaPlayer.create(TestSonido.this, R.raw.slayer); mp.start(); } }); In this case, R.raw.slayer represents an audio file called slayer.mp3 that is stored in the res/raw/ … Read more
This lets you give frequency, duration, and amplitude, and it is 100% .NET CLR code. No external DLL’s. It works by creating a WAV-formatted MemoryStream which is like creating a file in memory only, without storing it to disk. Then it plays that MemoryStream with System.Media.SoundPlayer. using System; using System.Collections.Generic; using System.IO; using System.Linq; using … Read more
I realize this question is fairly old but when I was struggling with the same problem I found a simple solution that hopefully will help anyone else looking to use the louder media speakers as opposed to the receiver speakers. The method I used was setting up the audio session with the DefaultToSpeaker option in … Read more
As some has pointed out in the comments, what you want to look into is PCM audio. In a nutshell, sound is a wave that travels through air. In order to capture that sound, we use a microphone, which contains a membrane which will vibrate as the sound waves hit it. This vibration is translated … Read more
This error (“Connection Rejected due to Limited resource”) typically happens when a T2 request is sent to a T1-only SCO listener. If you read the patch notes to version 5 you can get a discussion about this problem linux-bluetooth v5 patch notes
It is definitely possible, you need to mount /dev/snd, see how Jess Frazelle launches a Spotify container, from https://blog.jessfraz.com/post/docker-containers-on-the-desktop/ you will notice docker run -it \ -v /tmp/.X11-unix:/tmp/.X11-unix \ # mount the X11 socket -e DISPLAY=unix$DISPLAY \ # pass the display –device /dev/snd \ # sound –name spotify \ jess/spotify or for Chrome, at the … Read more
If you use MediaRecorder (the example, above) it will save compressed audio to a file. If you use AudioRecord, you can get audio samples directly. Yes, what you want to do should be possible.
yes,getByteFrequencyData results in a normalized array of values between 0 and 255. (it copies the data to the array it gets passed-in). the frequency bands are split equally, so each element N of your array corresponds to: N * samplerate/fftSize so, the first bin is 0. and, assuming a samplerate of 44100 and a <analyzerNode>.fftSize … Read more
An easier way to do this is using pydub module. recent addition of silent utilities does all the heavy lifting such as setting up silence threahold , setting up silence length. etc and simplifies code significantly as opposed to other methods mentioned. Here is an demo implementation , inspiration from here Setup: I had a … Read more
