Mp3 encoder - Audio - Arduino Forum

He’s got a file called PCM.ZIP and that includes a file called EncodeAudio.exe. He says: but the Arduino can only play 16 bit PCM 8kHZ audio mp3 & that mp3 should be coded using a encoder software That’s confusing… But, it does NOT play MP3… It plays MP3s that are decompressed (decoded) and then “encoded” to PCM.

In “File”, select “Export”, then “Export to WAV”. Select “Other uncompressed formats” as the type and then “Unsigned 8bit PCM” as the encoding. You just have to paste the audio file in an SD card to be able to play it with an Arduino or other card. Don’t forget to change the file name in the code.

the important step is to prepare the audio data.so very first we will need a mp3 file either you record one or get one from anywhere then open that file into Audacity and & click on format then select 16 bit pcm then go down & select frequency of audio to 8000hz & export the audio as mp3. Then open encode audio software & navigate to the audio file we generated froma audacity …

To encode your own audio samples, you’ll first need to down-sample the audio to 8 KHz, 8-bit mono sound, then convert it to a series of numbers that can be pasted into your Arduino program. Note that you’re only going to be able to store approximately 4 seconds of audio on the Arduino, so you might want to trim your clip first (e.g. using Quicktime).

See, the “EncodeAudio” application is a simple processing program that reads an audio file and copies its audio data to the clipboard in numeric form ( https://github.com/damellis/EncodeAudio ). Now is the time to open a new code window in your Arduino IDE and write the Arduino Sketch as shown below.

An MP3 Encoder for Arduino ? - Phil Schatzmann

So I decided to take this up and make LAME available as Arduino Library. LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL. It is considered as one of the best MP3 encoder at mid-high bitrates and at VBR. I used the latest current release version 3.100 which can be downloaded from Sourceforge as starting point.
