• 🎧 Audio File Size Calculator

    Estimate the file size of an audio recording based on sample rate, bit depth, number of channels, and recording duration.

    Size Per File 0 MB
    Total Storage 0 MB
    Uncompressed Bitrate 0 kbps
    Duration 0
    Sample Rate 0
    Bit Depth 0
    Channels 0
    Samples Per File 0
    💡 Tip: Higher sample rates, greater bit depths, more channels, and longer recordings all increase the size of an uncompressed audio file. This is especially important when estimating storage requirements for multitrack recording sessions.
    This calculator estimates the size of uncompressed PCM audio such as WAV or AIFF. Actual file sizes can vary slightly because of file headers and metadata. Compressed formats such as MP3, AAC, and OGG require bitrate-based calculations instead.

  • An Audio File Size Calculator can help musicians, producers, recording engineers, and home-studio users estimate how much storage their audio recordings will require. By entering the sample rate, bit depth, number of channels, recording length, and number of files, you can estimate the size of uncompressed audio such as WAV or AIFF files.

    Audio file size is affected by several factors. Higher sample rates create more samples every second, while higher bit depths require more data to represent each sample. Stereo recordings also require twice as many channels as mono recordings, and longer recordings naturally require more storage.

    For example, a stereo recording at 44.1 kHz and 24-bit will require considerably more storage than a mono recording at 44.1 kHz and 16-bit. Multitrack recording sessions can become especially large because every individual track creates another audio file or collection of audio files.

    This can be useful when planning home-studio storage, recording sessions, sample libraries, backups, cloud storage, and external hard-drive capacity. Estimating your storage needs ahead of time can help prevent running out of space in the middle of a recording project.

    Tip: Don't forget about the audio files you may not immediately see. Alternate takes, vocal comps, bounced stems, consolidated tracks, instrumental versions, session backups, and unused recordings can add up quickly. When planning storage for a music project, leave considerably more room than the final song itself will require.
