A lightweight Linux alternative to RightMark Audio Analyzer for evaluating audio files, loopback captures, and codec fidelity with precision spectral metrics. Key Features: * Precision Calibration WAV Synthesizer: Generates bit-exact 16-bit and 24-bit PCM WAV calibration signals at 44.1 kHz, 48 kHz, and 96 kHz including 1 kHz reference sine, 60 Hz + 7 kHz SMPTE twin-tone IMD, 20 Hz to 20 kHz logarithmic sweep, white noise, and dual-channel stereo crosstalk test probes. * Multi-Format Audio Decoding: Reads uncompressed PCM WAV directly and decodes FLAC, MP3, Ogg Vorbis, Opus, AAC, and M4A audio files via bundled FFmpeg into floating-point frames. * Windowed Radix-2 FFT Distortion Metrics: Applies a 4-term Blackman-Harris window with Welch spectral averaging to compute Total Harmonic Distortion (THD % and dB), THD+N (dB), Signal-to-Noise Ratio (SNR dB), Dynamic Range, Peak and RMS dBFS, Crest Factor, DC Offset, and Stereo Crosstalk (dB). * Harmonic Spectrum Plot & Lab Reports: Renders an interactive logarithmic frequency spectrum with H1 through H10 harmonic markers and exports HTML, CSV, and JSON lab reports.

They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install Audio Signal and Distortion Analyzer To install Audio Signal and Distortion Analyzer, simply use the following command: ``` sudo snap install audio-thd-analyzer ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
