๐ต Audio File Size Calculator
Calculates the file size of uncompressed PCM audio (WAV, etc.).
Enter a sample rate, bit depth, channel count (mono/stereo), and duration to calculate the file size of an uncompressed PCM audio file (WAV, etc.). Preset buttons for common quality levels like CD audio are also available.
How to use
- Enter the sample rate (Hz), bit depth (bit), and channel count, or pick a preset button.
- Enter the duration (minutes).
- The uncompressed file size is calculated automatically.
FAQ
What's the formula?
File size (bytes) = sample rate (Hz) ร bit depth (bit) ร channels ร duration (seconds) รท 8. For example, one minute of CD-quality audio (44.1kHz/16bit/stereo) comes out to about 10.09 MB.
Does this handle compressed formats like MP3?
No. This tool calculates the size of uncompressed PCM formats like WAV or AIFF. Compressed formats like MP3 vary in size depending on the compression algorithm and bitrate settings, which this tool doesn't model.
What do the presets represent?
Three common configurations: CD quality (44.1kHz/16bit/stereo), hi-res equivalent (96kHz/24bit/stereo), and voice-call quality (16kHz/16bit/mono).
