Audio File Info — View Duration, Bitrate, Sample Rate and Codec
Instantly analyse any audio or video file and display detailed technical information including codec, bitrate, channels, and more.
Why Check Audio File Information?
Understanding the technical properties of an audio file is essential for many professional and everyday tasks. Before editing, converting, or processing audio, you need to know its current specifications. Before submitting audio to a client or platform, you need to confirm it meets the technical requirements. SoundCuibu Audio Info reveals all the hidden technical data inside any audio or video file in seconds.
What Information Is Displayed
- Format and Container — The file container format (MP3, WAV, FLAC, MP4, MKV, etc.) and codec used for the audio stream.
- Duration — The total length of the audio in hours, minutes, and seconds.
- Bitrate — The data rate of the audio stream in kilobits per second (kbps). Higher bitrates generally mean better quality for lossy formats.
- Sample Rate — The number of audio samples per second, measured in Hertz (Hz). Common values are 44,100 Hz (CD quality) and 48,000 Hz (video standard).
- Channels — Mono (1 channel), Stereo (2 channels), or multi-channel (5.1, 7.1).
- Bit Depth — For uncompressed formats like WAV and FLAC: 16-bit, 24-bit, or 32-bit.
- Codec — The specific audio codec: MP3 (MPEG Layer 3), AAC, FLAC, Vorbis, Opus, PCM, etc.
- File Size — The total file size in megabytes.
Common Use Cases
- Verify client deliverables — Confirm an audio file meets the technical specification before delivery (e.g. 44.1 kHz, 24-bit WAV, stereo).
- Pre-conversion check — Identify the current format and bitrate before deciding how to convert.
- Troubleshooting — Diagnose why an audio file sounds poor (very low bitrate) or why it is incompatible with a player.
- Archive verification — Confirm FLAC files are truly lossless and not re-encoded from a lossy source.
Checking Video Audio Tracks
The Audio Info tool also accepts video files (MP4, AVI, MOV) and reports the properties of the embedded audio track. This is useful for verifying the audio quality inside a video before extracting it.
How it works

FAQ
What file formats does Audio Info support?
MP3, WAV, FLAC, OGG, AAC, M4A, OPUS, WMA, and video formats MP4, AVI, and MOV.
What information does the tool display?
Duration, format, codec, bitrate, sample rate, channel count, bit depth, and file size.
Does the tool modify my file in any way?
No. Audio Info is read-only. It analyses the file and displays information without making any changes.
Can I check the bitrate of an MP3 file?
Yes. The bitrate is displayed in kbps. Common values are 128, 192, and 320 kbps.
Can I check if a FLAC file is truly lossless?
The tool shows the codec and bit depth. A genuine FLAC file will show FLAC codec with 16 or 24-bit depth. However detecting if a FLAC was re-encoded from MP3 requires spectral analysis.
Does it show metadata like artist and album?
Basic metadata is shown where available. For full metadata editing, use the Audio Metadata tool.
Is the tool free?
Yes, completely free. No account or software needed.
Is my file kept private?
Yes. Files are processed securely and deleted within 12 hours.
Can I analyse video files too?
Yes. Upload an MP4, AVI, or MOV file to see the audio track properties within the video container.
