Read Music File Details in MediaInfo

At a glance

MediaInfo non-destructively reveals real technical details of music files, separating general container fields from true audio stream properties. It supports a wide range of formats and export options, helping users verify codec, bitrate, and sample rate without file modification. Ideal for collectors, it aids in uncovering mislabelled or misrepresented music and complements other metadata tools.

MediaInfo is a versatile open-source tool designed to extract and present both technical details and tag data from audio and video files. Its utility lies in allowing users to accurately identify the real properties of their media—beyond what is claimed by filenames or user-editable tags—without modifying or renaming original files. MediaInfo supports a wide spectrum of audio formats and provides structured presentations of both general container information and specific audio stream properties, making it an ideal choice for verifying music file authenticity and technical characteristics.

When and why MediaInfo helps

For music collectors, curators, or anyone seeking confidence in their files' provenance and quality, MediaInfo offers clear advantages. It is particularly beneficial when you need to:

• Discern between overall file (container) attributes and embedded audio track specifics.
• Read essential details such as codec type, bitrate (CBR/VBR), sample rate, and number of channels.
• Access tag metadata for context, such as title, artist, album, and track number.
• Investigate the presence of multiple streams or tracks within a single file.

This distinction is crucial when encountering music files labeled as lossless FLAC, high-bitrate MP3, or any format where origin is uncertain. Since file conversion or renaming often obscures the actual encoding, MediaInfo equips you with authoritative data directly from the file's structure and embedded tags.

Installing and opening a file

1. Acquire MediaInfo: Download the appropriate version for your platform (Windows, macOS, Linux, and others are supported). Web-based analysis is also available via MediaInfoOnline.
2. Install and launch: Run the installer. For those preferring not to install software, the web utility offers a rapid alternative.
3. Load your music file: Use drag-and-drop or the open file function within the interface to select and analyze an audio file (MP3, FLAC, AAC, etc.).

All operations are read-only; your files remain unaltered throughout the analysis process, preserving archival originals or verified sources.

Navigating MediaInfo’s displays

Upon loading a file, MediaInfo by default displays a summary overview. Users can switch between various viewing modes—Text, Tree, Sheet, and HTML—to control the presentation granularity. Typically, information is divided into:

• General/Container: This block summarizes the container format (such as FLAC, MPEG Audio), total file size, duration, average bitrate, the encoding tool used, and global tag information (title, artist, album, track number).
• Audio Streams: Specific to each embedded audio track, reporting codec (MP3, AAC, FLAC, etc.), codec profile or version, bitrate mode and value, channel count (mono, stereo), sample rate (e.g., 44.1 kHz), bit depth for lossless formats, and other technical details.

Clear separation between these categories allows immediate assessment, such as identifying whether a file's internal stream matches the expected audio type (e.g., confirming that a FLAC-labeled download contains actual lossless audio rather than a misrepresented MP3 stream).

Distinguishing general and stream fields

A defining feature of MediaInfo is its precise separation of general (container-level) and audio stream (track-level) fields. Understanding the distinction is essential for interpreting any report:

• General/Container fields: Metadata like Format, File size, Duration, Album, and Track number. These describe the file as a whole and are not direct indicators of audio content quality.
• Audio fields: Technical attributes such as Codec ID, Bitrate, Sampling rate, Channels, and Bit depth. These pertain specifically to the embedded audio and reflect actual sound encoding details.

This helps spot mismatches—such as an ostensibly lossless title where the audio stream reveals compressed, lossy encoding. By comparing these sections, users can verify or dispute claims without relying solely on easily modified tags.

Practical verification process

1. Open a file with MediaInfo: Opt for the Tree or Sheet mode to access a comprehensive breakdown.
2. Consult the General section: Confirm that listed container format, file size, and duration are consistent with expectations for the file type.
3. Examine the Audio fields: Note whether the codec, bitrate, and sample rate conform to claimed quality levels. For instance, a purportedly lossless file showing MP3 as the codec and a low bitrate should raise doubts.
4. Reference descriptive tags: Information such as title or album can be corroborative but is not technically verified. Treat these as user-supplied data.

Example:
MySong_Lossless.flac reports:

• General: FLAC format, 3:42 duration, 21MB size.
• Audio: FLAC codec, 16-bit depth, 44.1kHz sample rate, stereo.

These properties align with typical CD-quality lossless audio. Conversely, a file named MySong_Lossless.mp3 with:

• General: MPEG Audio format.
• Audio: MP3 codec, 320kbps bitrate, 44.1kHz sample rate.

would not be genuinely lossless, regardless of embedded tag claims.

Exporting MediaInfo data

MediaInfo supports exporting its analysis in several formats—plain text, CSV, and HTML—via built-in export or save functions in the graphical user interface. These exports maintain the separation of general container and audio stream data, facilitating documentation, sharing for troubleshooting, or batch processing of music library inventories—compatible, for example, with local music inventory CSV workflows.

Comparing MediaInfo with other tools

MediaInfo excels at quick, structured inspection of single files or small batches. Users needing deeper analysis, such as examining codec parameters at a forensic level, may complement it with ffprobe. Those focused on music collection management or tag organization might prefer exporting a music inventory from Mp3tag, especially when working with large archives or preparing databases.

Next steps: checking batch files

After learning the interface and interpreting MediaInfo's results, consider sampling batches of your collection. Noting differences in encoding or metadata among similarly labeled files can reveal sources of mislabeling or inconsistencies, helping streamline cataloguing and prevent playback surprises down the line.
