In order to start your Arduino PCM Audio experiments, just pick a small MP3 audio file of your choice at first, and then convert it into a 16bit PCM 8kHz monoaural MP3 audio file. The far-famed Audacity software will help you to do this conversion at ease (see a sample screen snip below).
I need to get wav with 16khz mono 16bit sound properties from any mp3 file. I was trying. ffmpeg -i 111.mp3 -ab 16k out.wav, but I got wav with the same rate as mp3 (22k). Please, help to construct right command line. mp3. wav. sample-rate. Share. Have been unable to create a WAV file with the following export specs: PCM, 8bit, Mono, 8khz. Have read all of the posts on this topic, tried them, none seem to work. Using Windows 7 Ultimate, 64-bit, SP1. Audacity 2.03, downloaded using exe module on 09-13-13. Have recorded a brief voice message using USB headset, mono mode. Must be exported to above specs in order to upload into a medical PCM stands for Pulse Code Modulation and commonly uses the file extensions .wav or .cda. There are quite a few other combinations of bits per sample and samples per second which may be used. We have included calculations for the most common mono (one channel) and stereo (two channel) settings. Mono. Formula: WAV 16-bit PCM is eminently suitable whenever you want to burn your exported file to an audio CD. WAV (Microsoft) signed 24-bit PCM No options for this format: 24-bit PCM gives higher quality than 16-bit PCM, but takes up more space. WAV (Microsoft) 32-bit float No options for this format: 32-bit float WAV is a lossless format, a maximum
Show activity on this post. I am currently having a bit of trouble converting an AudioInputStream from MPEG1L3, 44.1 kHz, stereo with unknown bits per sample, unknown frame size and unknown frame rate to 48KHz 16bit stereo signed BigEndian PCM.

WAV. Waveform Audio File Format ( WAVE, or WAV due to its filename extension; [3] [6] [7] pronounced / wæv / or / weɪv / [8]) is an audio file format standard, developed by IBM and Microsoft, for storing an audio bitstream on personal computers. It is the main format used on Microsoft Windows systems for uncompressed audio.
Let's say we recorded a 5-minute CD-quality audio (at 16-bit bit depth) with a sample rate of 44.1 kHz. audio file size = bit depth * sample rate * duration of audio * number of channels. audio file size = 16 bits/sample * 44.1 kHz (or samples/sec) * 5 minutes * 2 channels. audio file size = 16 bits/sample * 44,100 samples/sec * 300 seconds * 2
Hi - I am trying to convert audio recording that was previously recorded from 16000 Hz to 8000 Hz. I’d like to change this without changing the audio drastically. I need the recording to be saved as (which is compatible with Five9 software): WAVE audio ITU G.711 mu-law mono 8000 Hz Typically, I can change the Hz in the bottom left corner, but in recent weeks that hasn’t worked for me with
