Sample Rate Checker

What is a sample rate checker?

A sample rate checker reads your audio file and reports its sample rate (Hz), bit depth, channel count, and codec — the metadata that determines whether your track meets each streaming platform's delivery specs. Our free sample rate checker compares your file against Spotify, Apple Music, and YouTube audio standards so you can fix delivery issues before uploading.

Audio sample rate standards explained

Sample rate is the number of audio samples per second (Hz). CD quality is 44.1 kHz, while most streaming platforms accept 44.1 kHz and 48 kHz, with some supporting up to 96 kHz. Higher sample rates capture frequencies above human hearing but create larger files with no audible benefit for most listeners. Bit depth (16-bit for CD, 24-bit for studio) controls dynamic range. Most platforms recommend 24-bit WAV masters at 44.1 or 48 kHz.

Streaming platform requirements

Why sample rate matters for streaming

Each streaming platform transcodes your master into multiple formats for different playback devices. If your file exceeds the platform's preferred sample rate, it will be downsampled — sometimes with audible artifacts. If your bit depth is too low, you lose dynamic range headroom. Uploading at the platform's preferred spec (usually 24-bit / 44.1 kHz WAV) gives you the best balance of quality and compatibility.

How to fix sample rate issues

If your file is at the wrong sample rate, re-export from your DAW at the target rate (44.1 kHz for Spotify, 48 kHz for video/YouTube). Avoid upsampling — converting a 44.1 kHz file to 96 kHz adds no quality and wastes space. Use a quality sample-rate converter (like SoX or iZotope RX) if you must convert. Always deliver 24-bit WAV masters when possible; if your source is 16-bit, do not upconvert to 24-bit — just deliver the 16-bit file.
