How to Convert raw-audio to FLAC?

  1. Click the “Choose Files” button to select your raw-audio files.
  2. Click the “Convert to FLAC” button to start the conversion.
  3. When the status change to “Done” click the “Download FLAC” button

Easy to Use

Simply upload your raw-audio files and click the convert button. You can also batch convert raw-audio to FLAC format.

Best Quality

We use both open source and custom software to make sure our conversions are of the highest quality. In most cases, you can fine-tune conversion parameters using “Advanced Settings” (optional, look for the icon).

Free & Secure

Our raw-audio to FLAC Converter is free and works on any web browser. We guarantee file security and privacy. Files are protected with 256-bit SSL encryption and automatically deleted after 8 hours.


Raw-audio is a headerless PCM sound file: nothing but the digital samples themselves, with no metadata, no compression, and no marker identifying where the audio begins. A WAV file is essentially the same data with a short descriptive header attached. Raw-audio appears most often as the output of audio hardware, DSP pipelines, and telephony systems, and as the intermediate stage between processing steps.

 

How to open a raw-audio file?

Import it into Audacity using File → Import → Raw Data. You will be asked for the encoding, byte order, channel count, and sample rate, since the file itself does not record them.

 

Common defaults are 16-bit signed PCM at 44,100 Hz or 48,000 Hz; telephony recordings are frequently 8-bit at 8,000 Hz. FFmpeg and SoX can play and convert raw-audio from the command line once you supply the same parameters. Save the result as WAV or MP3 so the settings travel with the file from then on. You can also convert the file with our RAW to MP3 tool.

Free Lossless Audio Codec (FLAC) is a file format that shrinks an audio file’s size, which, as the word “lossless” in the name implies, results in no loss in audio quality or original data. FLAC accomplishes this by using an algorithm that compresses the file to approximately 50 to 70 percent of its original size.

 

How to open a FLAC file?

The default program for opening a FLAC file is VLC media player. Other details about FLAC include that it is unpatented, permits music reproduction, is compatible with Telephony Application Programming Interface (TAPI), and is not subject to digital rights management (DRM).

 

Additionally, codecs that can implement FLAC include FFmpeg, Flake and FLACCL for encoding, and Audiocogs for decoding. Lastly, as the word “free” in the name suggests, FLAC is open-source software.
