Open models for acoustic monitoring

The model listens to equipment through an ordinary microphone and notices when the sound changes: a bearing hums differently, a pump runs rough, an unfamiliar knock appears on the shop floor. Such a system does not diagnose anything; it gives you a reason to inspect a unit before it fails. It runs locally on modest hardware and never sends recordings to a cloud.

YAMNet

Google · USA

A tiny model covering 521 sound events, including alarms, breaking glass and screams: it fits on a microcontroller and runs without a GPU. A microphone can capture people voices, which is personal data, so check the procedure with a lawyer.

  • Fast sound labelling right on the device
  • Detecting alarm sounds on a site
  • Picking interesting fragments out of a continuous recording

MLPerf Tiny Anomaly Detection

MLCommons · USA

A reference autoencoder for finding anomalies in machine sound: it learns only from recordings of a healthy unit and flags deviations. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • Listening to a machine tool, pump or conveyor
  • Flagging deviations from a unit usual noise
  • Training on your own recordings of healthy equipment
Sizes
a tiny fully connected autoencoder sized for microcontrollers

BirdNET

Cornell Lab of Ornithology and Chemnitz University of Technology · USA and Germany

Recognition of more than 6000 bird species by voice, the baseline tool for acoustic monitoring of an area. A microphone on site also records people voices, which is personal data, so check the procedure with a lawyer.

  • Long-term monitoring of the sound background of a site
  • Assessing biodiversity for an environmental review
  • Selecting events from round-the-clock recordings

PANNs

University of Surrey · UK

The classic set of convolutional networks that label sound across the 527 AudioSet categories, from machinery noise and alarms to breaking glass and screams. The system does not make a diagnosis, it gives you a reason to check the unit before it fails. A microphone can also capture people voices, which is personal data, so check the procedure with a lawyer.

  • Labelling what is happening in a microphone recording
  • Detecting alarms, breaking glass, screams
  • A base for your own model tuned to one shop floor

CED

Xiaomi · China

Compact sound-labelling models from 5.5M to 86M, with ONNX and INT8 builds that run on an ordinary CPU and on a board next to the equipment. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • Labelling sound on modest hardware and on site
  • Detecting alarm sounds and abnormal noise
  • Fine-tuning for your own set of equipment sounds

Dasheng

Xiaomi · China

A general-purpose audio encoder trained on 272 thousand hours of speech, music and noise: it gives features on top of which you train your own classifier of abnormal sounds. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • Audio features for your own anomaly model
  • Finding similar fragments in a recording archive
  • Fine-tuning for the sounds of one production line

OpenBEATs

Carnegie Mellon University and co-authors (the ESPnet project) · USA

A fully open reproduction of BEATs: code, training recipes and weights are all published. Teams pick it when they need a transparent base for their own sound model. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • A transparent base for your own audio model
  • Fine-tuning on your own equipment recordings
  • Labelling sound events

Perch

Google DeepMind · USA

A model for acoustic monitoring of nature: it recognises about 15,000 species and provides features for your own tasks, and the license allows commercial use. A microphone on site also records people voices, which is personal data, so check the procedure with a lawyer.

  • Monitoring the sound background of a site or water area
  • Environmental audio features for your own model
  • Selecting events from round-the-clock recordings

EAT

Shanghai Jiao Tong University and Peng Cheng Laboratory · China

A self-supervised sound understanding model that is markedly cheaper to train on your own data than its predecessors. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • Training your own audio model on modest hardware
  • Audio features for spotting abnormal operating modes
  • Labelling sound events on a site

DASS

MIT CSAIL and MIT-IBM Watson AI Lab · USA

A sound understanding model built on state spaces instead of a transformer: it handles recordings hours long, which suits continuous listening to a production line. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • Processing long continuous recordings
  • Finding a rare event across a multi-hour shift
  • Labelling sound events on a site
Sizes
30M (small) and 49M (medium)

HeAR

Google · USA

A model for health sounds: coughing, breathing, throat clearing. It provides features on top of which a researcher builds their own model and draws no conclusions about illness itself. It does not replace a doctor; decisions are made by a specialist. Voice recordings are personal data, so check the procedure with a lawyer.

  • Features of cough and breathing sounds for your own model
  • Research projects in health acoustics
  • Selecting cough and breathing fragments from a recording

BEATs

Microsoft · USA

A self-supervised sound understanding model that became the base for many current systems: teams take it as a starting point and fine-tune it on their own equipment sounds. The system does not make a diagnosis, it gives you a reason to check the unit before it fails.

  • A base for your own sound understanding model
  • Audio features for spotting abnormal operating modes
  • Labelling sound events on a site
