Versions:
Chromaprint is a lightweight, open-source C library developed by AcoustID that enables applications to generate compact acoustic fingerprints from raw audio streams, providing a reliable way to identify near-duplicate recordings regardless of format, bitrate, or minor mastering differences. Designed for integration into music-management tools, media servers, and automated tagging pipelines, the library exposes a simple API that accepts PCM audio data and returns short, hash-like identifiers that can be submitted to the AcoustID web service for lookup against its community-maintained database of more than 50 million tracks; this makes it equally useful for desktop organizers such as MusicBrainz Picard, cloud-based deduplication services, and headless servers that need to verify rips against known releases. Version 1.6.0 refines the algorithmic core for faster 32-bit and 64-bit processing, lowers memory usage during batch analysis, and guarantees binary compatibility with the previous 1.5 branch, while the earlier v1.5 series remains available for legacy builds that target older toolchains. The codebase is platform-agnostic, ships with CMake build scripts, and offers optional bindings for Python, Java, and .NET so that developers can embed fingerprinting into cross-platform workflows without writing native code. Because fingerprints are only 120–160 bytes apiece, entire music libraries can be scanned and cached locally, allowing offline comparison and incremental updates whenever new tracks arrive. Chromaprint is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
