Raw audio is uncompressed pulse-code modulation (PCM) sound stored with no header at all — just a continuous stream of sample values. Because the file carries no description of itself, the sample rate, bit depth, channel count, and byte order have to be supplied by whoever opens it. That makes raw audio awkward to share but very useful in audio programming, embedded devices, and recovery work, where a plain stream of samples is exactly what is needed.

 

How to open a raw audio file?

The standard tool is Audacity. Use File → Import → Raw Data, then set the encoding, sample rate, and channels to match the file.

 

If you do not know the correct settings, start with 16-bit signed PCM, 44,100 Hz, stereo, and adjust until the audio sounds normal — wrong settings usually produce noise or a chipmunk-like pitch. Command-line users can play or convert raw audio with FFmpeg or SoX. Converting to a self-describing format such as WAV or MP3 saves you from repeating the guesswork. You can also convert the file with our RAW to WAV tool.

MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. MP3 files are the most widely-used audio file for consumers. Due to small size and acceptable quality, MP3 files are accessible to a wide audience, as well as easy to store and share.

 

How to open an MP3 file?

Because MP3 files are so prevalent, most major audio playback programs support them. Simply clicking on the file will open it in iTunes or Windows Media Player, depending on your preferred platform. Users can also preview MP3 files.

 

Another program that can open MP3 files is VLC media player. Keep in mind that two other file types use the MP3 extension. They are Masterpoint green points data, which is obsolete; and TeslaCrypt 3.0 ransomware encrypted file, which is malware that demanded ransom in bitcoins, but is thankfully now deactivated and no longer a threat.
