Here are 3 free online audio bitrate calculator websites. Audio bitrate (like 128 kbps, 320 kbps, etc.) calculation comes in handy when you have to rip some CD, DVD, etc. You will have a good idea about what should be the optimum level of audio bitrate for making the video of a particular size. So, let’s say you have 700 MB CD or 4.7 GB DVD, you can check the optimal audio bitrate level to burn it.

You can calculate audio bitrate for a compressed audio file (like MP3) or uncompressed audio file (like WAV, AIFF, etc.), depending on the website you are using. You can add audio length (in hours, minutes, and seconds), the sampling rate (44100 Hz, 88200 Hz, etc.), channels, and other details, and find out the required audio bitrate.

Let’s check these free online audio bitrate calculators one by one.

The Audio Archive

Audio Bit Rate and File Size Calculator

The Audio Archive website provides a separate tool for audio bitrate calculation. Its name is “Audio Bit Rate and File Size Calculator“. You can open the homepage of that tool using this link. Once you’ve accessed that page, you need to add:

  • Sample Rate (Hz): It can be 44.1 kHz, 88.2 kHz, 96 kHz, etc.
  • Word length: Anything like 1, 1.0347, 4.174, etc., and
  • Channels.

As soon as you enter these values and click somewhere else, the audio bitrate for uncompressed and compressed audio is visible immediately.

As the name of this tool indicates, you can also use it to calculate the size of audio. Enter the file recording time (in minutes), number of files in that audio, and it will show the size of audio files, both in compressed and uncompressed modes.

Online Bitrate Calculator

Online Bitrate Calculator

Online Bitrate Calculator (Homepage) is also a nice option to use as an audio bitrate calculator. But, it works in a bit different manner. You have to enter movie or audio information, like length (in hours, minutes, and seconds), MB required for that much length, and audio bitrate. After that, you need to press the Calculate button. Finally, it shows the output for DivX3, DivX5/x264, and DivX4.

Thus, instead of adding the sample rate, channels, etc., you need to enter the audio bitrate and other details. Based on those details, it shows the results. So, you need to adjust audio bitrate intelligently and then you will have an idea what audio bitrate will be good for a particular DivX format disc. Though this is not a direct way for audio bitrate calculation, it works when you have a little to no idea about what audio bitrate level should be good to create a CD/DVD with a specific audio size.

Audio File Size Calculator

Audio File Size Calculator

Audio File Size Calculator (Homepage), as the name suggests, is handy to get the file size for compressed and uncompressed audio files. However, it can also be used to check audio bitrate for an uncompressed audio file (AIFF, WAV, etc.). What you need to do is enter the audio duration (in hours, seconds, minutes, and milliseconds), set the sample rate, channels, and bit depth. Finally, you will get the output showing you the audio bitrate and file size (in binary and decimal).

The website, as mentioned in starting, also lets you check the file size for compressed audio (by adding the audio bitrate), but it can’t help you check audio bitrate for compressed audio.

If you need software for audio bitrate calculation, then you should check this list.

The Conclusion:

These are the best options available as online audio bitrate calculator websites. Among all these websites, “The Audio Archive” seems to be a better option. It gives output for compressed and uncompressed audio files and options to calculate audio bitrate are pretty simple.
