Audio Analyzer vs Audiolab
A side-by-side look at the Audio Analyzer and Audiolab MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Audio Analyzer for multimedia process work; choose Audiolab for multimedia process as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Audio Analyzer when
- You need dedicated capabilities in the Multimedia Process domain.
- You want tools like
audio_info, spectral_features, harmonic_analysis.
Choose Audiolab when
- You need dedicated capabilities in the Multimedia Process domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
AUDIOLAB_API_KEY, AUDIOLAB_API_BASE, AUDIOLAB_TIMEOUT_MS. - You want tools like
analyze_loudness, check_target, analyze_timeseries.

audio_infoBasic file info: duration, sample rate, sample countspectral_featuresBrightness, richness, loudness, texture, timbre (MFCCs), frequency band energy, spectral contrast, dynamic range, LUFS loudness, stereo fieldharmonic_analysisKey detection, pitch class distribution, tonnetzrhythm_analysisTempo (BPM), beat positions, tempo stabilityfull_analysisEverything above in one call, plus percussive character (HPSS), stereo field, and section boundaries. Recommended workflow: call without resolution first to get summary + section map, then zoom into interesting sections with `start_time`/`end_time` at high resolutioncompareA/B two tracks -- analyses both and returns a compact diff table

Frequently asked questions
Audio Analyzer is categorized under Multimedia Process and uses an install path we have not confirmed yet. Audiolab belongs to Multimedia Process and uses a local stdio subprocess. Pick Audio Analyzer for multimedia process work and Audiolab for multimedia process.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. Audio Analyzer has no confirmed install command yet — follow its own setup instructions.
Audio Analyzer has no declared pricing — check the project's own site. Audiolab has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add audio-analyzer and audiolab as separate keys in the same mcpServers object, and your assistant will call tools from either one.
