Audio Metadata Viewer

About Audio Metadata Viewer

This online audio metadata viewer reads and displays all metadata information from your audio files including ID3 tags, album art, technical specifications, and more. It supports all common audio formats (MP3, FLAC, M4A, OGG, WAV, OPUS, AAC) and displays comprehensive information about bitrate, codec, sample rate, and embedded tags.

What audio formats are supported?

All common audio formats: MP3, FLAC, M4A/AAC, OGG Vorbis, OPUS, WAV, AIFF, APE, WV (WavPack), and more. The tool reads ID3v1, ID3v2, Vorbis comments, iTunes/MP4 tags, and other metadata formats.

What is metadata?

Metadata is information about the audio file embedded within the file itself. This includes: song title, artist name, album name, release year, genre, album art, track number, composer, and technical details like bitrate and sample rate.

What are ID3 tags?

ID3 tags are metadata containers used primarily in MP3 files. ID3v1 (older, limited) stores basic info in last 128 bytes. ID3v2 (newer, extensive) supports album art, lyrics, multiple artists, and much more. This tool reads both versions.

Can I see the album art?

Yes! If your audio file has embedded album art (cover image), it will be displayed at full size. Most modern audio files from iTunes, Spotify downloads, or properly tagged music will have album art embedded.

What technical information can I see?

Format/container (MP3, FLAC, etc.), Codec (audio compression method), Bitrate (audio quality in kbps), Sample rate (in kHz), Channels (mono/stereo), Duration, File size, Encoding settings, Lossless/lossy status.

What is bitrate and why does it matter?

Bitrate (in kbps) indicates audio quality and file size. Higher bitrate = better quality + larger file. Common bitrates: 128 kbps (low quality MP3), 192 kbps (good quality), 320 kbps (high quality MP3), 1411 kbps (CD quality). FLAC is lossless and varies by content.

What does sample rate mean?

Sample rate (in kHz) is how many times per second audio is sampled. 44.1 kHz (CD quality, most common), 48 kHz (DVD/video standard), 96 kHz or 192 kHz (high-resolution audio). Higher sample rate can capture higher frequencies but increases file size.

What's the difference between lossless and lossy?

Lossless (FLAC, ALAC, WAV): Perfect quality, no data lost, larger files. Lossy (MP3, AAC, OGG): Compressed with some quality loss, smaller files. Lossless is identical to original, lossy removes inaudible parts to save space.

Can I edit the metadata?

This tool is view-only. To edit metadata, you need dedicated tag editors like: Mp3tag, MusicBrainz Picard, Kid3, or built-in editors in music players like iTunes or foobar2000.

Why doesn't my file have metadata?

Some audio files don't have embedded metadata: Files from voice recorders, raw audio recordings, YouTube downloads (sometimes), old files before tagging was common, or files that were never properly tagged. You can add metadata using tag editing software.

Is my audio file safe?

Absolutely! All metadata reading happens directly in your browser. The audio file is never uploaded to any server. Only the metadata is extracted and displayed locally.

What is the file size limit?

The tool can read metadata from files up to 100MB. Metadata reading is very fast as it only reads the tag portions of the file, not the entire audio data.
