Complete Guide: Audio Metadata Viewer
Everything you need to know about using this tool effectively
The Audio Metadata Viewer shows the technical details of any audio file. Upload your file to instantly see its duration, sample rate, number of channels, and other properties. This is useful for verifying audio specifications before editing, mixing, or distributing files. All analysis happens in your browser with no file uploads.
This tool decodes your audio file using the Web Audio API and reads the properties of the resulting AudioBuffer, including sample rate, channel count, and precise duration in samples and seconds.
Checking Sample Rate Before Mixing
Mismatched sample rates cause pitch and timing issues in a mix. Check that all your files are at the same rate before importing them into your DAW.
Verifying Channel Count
Confirm whether a file is mono or stereo before using it. Mono files placed on stereo tracks (or vice versa) can cause unexpected panning or level issues.
Checking File Duration
See the exact duration of an audio file down to the sample level. Useful for timing audio to video, checking loop points, or verifying recording length.
Quick Format Identification
When you receive audio files from clients or collaborators, quickly check their technical specifications without opening a full audio editor.
Upload Your Audio File
Click the upload area or drag and drop any audio file into the tool.
Click Analyze
The tool decodes your file and displays its metadata: duration, sample rate, number of channels, and total samples.
Review the Details
Check the displayed information against your requirements. You can also play back the audio to verify its content.
CD-quality audio is 44,100 Hz sample rate, 16-bit, stereo (2 channels)
Professional video production typically uses 48,000 Hz sample rate
If the sample rate shows 44,100 Hz but you expected 48,000 Hz, you will need to resample before mixing with other 48kHz files
Mono files have 1 channel, stereo has 2, and surround sound can have 6 or more
What is a sample rate?
Sample rate is how many audio snapshots (samples) are captured per second. CD quality is 44,100 Hz (44,100 samples per second). Higher sample rates like 48,000 Hz or 96,000 Hz capture more detail but produce larger files.
What does the channel count mean?
Channels represent separate audio streams. Mono has 1 channel, stereo has 2 (left and right), and surround sound formats have more. Most music is stereo, while voice recordings are often mono.
Can this tool read ID3 tags or embedded metadata?
This tool shows the audio properties from the decoded audio data (sample rate, channels, duration). It does not currently read embedded metadata tags like ID3 (artist, title, album) which are stored separately in the file container.
Does this upload my file?
No. All analysis happens locally in your browser using the Web Audio API. Your file never leaves your device.
