View Audio Metadata
Free online audio metadata viewer. View duration, bitrate, sample rate, and more. No download required, process locally for privacy.
The audio metadata viewer parses and displays various metadata information embedded in audio files. This information falls into two categories: technical parameters and tag information, helping you fully understand audio file attributes. Whether confirming bitrate and sample rate to evaluate quality, or viewing title, artist, and album tags to organize your music library, this tool handles it all with one click.
Technical parameters include bitrate, sample rate, channel count, duration, and encoding format—these parameters determine audio quality and file characteristics. Tag information includes title, artist, album, year, and cover art—this information identifies and categorizes audio content. Typical applications include audio quality inspection, file information confirmation, and batch viewing of metadata to classify and organize audio materials.
All audio file processing is performed entirely in your browser locally—files are never uploaded to any server. This means your private recordings, music files, and commercial audio materials remain on your device throughout the entire viewing process, maximizing privacy and data security.
How to View Audio Metadata
Upload Audio File
Click the upload area or drag and drop audio files. Supports mainstream formats including MP3, WAV, FLAC, and AAC. You can select multiple files at once.
Auto Parse Metadata
The tool automatically parses technical parameters and tag information from audio files. Parsing is performed locally in your browser with real-time result display.
View Detailed Information
View technical parameters including bitrate, sample rate, channels, duration, and format, as well as tag information like title, artist, and album.
Optional Export
If you need to save metadata information, you can choose to export as a text file. Convenient for subsequent organization, archiving, and sharing of audio file details.
Core Features
Technical Parameters Display
Displays core technical parameters including bitrate, sample rate, channel count, duration, and encoding format. Helps you fully understand audio file quality characteristics and technical specifications for quality assessment and device adaptation.
Tag Information
Displays tag information including title, artist, album, year, and cover art. This information identifies and categorizes audio content, helping you organize music libraries and confirm file sources.
Format Recognition

Use Cases
Audio Quality Inspection
Confirm audio bitrate and sample rate to evaluate quality. Higher bitrate and sample rate typically mean better quality—viewing technical parameters lets you quickly determine whether audio files meet expected quality standards.
File Information Confirmation
View detailed parameters of audio files to confirm technical information like format, duration, and channels. Avoids playback compatibility issues caused by unclear information, ensuring audio plays normally on target devices.
Audio Organization
Batch view metadata of audio files to classify and organize based on artist, album, year, and other tag information. Keeps music libraries and audio material collections organized, convenient for subsequent searching and use.
FAQ
What metadata can I view?
This tool can view two types of metadata in audio files. Technical parameters include bitrate, sample rate, channel count, duration, and encoding format—these parameters determine audio quality and file characteristics. Tag information includes title, artist, album, year, and cover art—this information identifies and categorizes audio content. Specific viewable fields depend on audio format and whether the file itself contains complete tag information.
Can I edit metadata?
This tool focuses on metadata viewing functionality and does not currently support direct editing. If you need to modify audio tag information, you can use specialized audio tag editing tools. The viewing function helps you confirm current file metadata status, providing reference for subsequent editing. Exported metadata information can also serve as a comparison basis during editing.
Is metadata related to audio quality?
Technical parameters in metadata are closely related to audio quality. Higher bitrate means more audio data and typically better quality; higher sample rate enables wider frequency range reproduction and more refined quality. Channel count determines spatial sense of sound—stereo is more immersive than mono. Tag information like title and artist is unrelated to quality, only used for identifying and categorizing audio content.
Can I view metadata for multiple files?
Yes. This tool supports batch viewing. You can upload multiple audio files at once, and the tool will sequentially parse and display metadata information for each file. Batch viewing is particularly suitable for organizing large audio collections, quickly understanding technical parameters and tag information for each file, convenient for classification, archiving, and quality screening. The number of files for batch viewing is only limited by your device's available memory.
What are bitrate and sample rate?
Bitrate refers to the number of bits of audio data transmitted per second, measured in kbps—higher bitrate means better quality, common values range from 64 to 320kbps. Sample rate refers to the number of times audio signals are sampled per second, measured in kHz—higher sample rate enables wider frequency range reproduction, common values are 44.1kHz (CD quality) and 48kHz (professional production). Together, they determine audio quality level.
What audio formats are supported?
This tool supports metadata viewing for mainstream audio formats including MP3, WAV, FLAC, AAC, OGG, and M4A. These formats cover most everyday use and professional production scenarios. Different formats may support different metadata fields—for example, MP3 uses ID3 tags, FLAC uses Vorbis comments. The tool automatically parses and displays available metadata information based on format.
