## Overview

Calculate MD5, SHA-1, SHA-256, and SHA-512 hashes to verify file integrity and detect any changes. Useful for validating backups, downloads, or file transfers.

## Inputs

- **Audio File** (file): Select an audio file to hash
- **Hash Algorithm** (select)

## When to use

- Verifying that an audio file downloaded from a server or shared online was not corrupted or altered during transmission.
- Confirming the integrity of large audio archives and backups over time to detect silent data corruption or bit rot.
- Generating unique cryptographic fingerprints for audio tracks to catalog, identify, or register digital assets.

## How it works

- Upload your audio file directly into the secure browser-based interface.
- Select your preferred cryptographic hash algorithm, such as MD5, SHA-256, or choose to generate all available hashes.
- Click the generate button to process the file and instantly view the calculated checksums in a clean JSON format.

## Use cases

- Podcast producers verifying that their master audio files match the versions uploaded to distribution platforms.
- Sound designers creating unique hash identifiers for sound effect libraries to prevent duplicate entries.
- Archivists validating digital audio preservation masters against original checksum manifests during migration.

## Frequently asked questions

### What audio file formats are supported by the Audio Hash tool?

The tool supports all standard audio file formats, including MP3, WAV, FLAC, AAC, OGG, and M4A, up to a maximum file size of 500MB.

### Does this tool upload my audio files to an external server?

No, the cryptographic hash calculation is performed entirely locally within your web browser, ensuring your audio files remain private and secure.

### Which hash algorithm should I use to verify file integrity?

SHA-256 or SHA-512 are highly recommended for secure integrity checks, while MD5 and SHA-1 are suitable for quick legacy verification.

### Can a change in audio metadata alter the generated hash value?

Yes, any change to the file's metadata, tags, or audio data will result in a completely different cryptographic hash.

### How do I compare two audio files using their hashes?

Generate the hash for both files using the same algorithm; if the resulting checksum strings match exactly, the files are identical.
