aclnet

Use Case and High-Level Description

The AclNet model is designed to perform sound classification and is trained on internal dataset of environmental sounds for 53 different classes, listed in file <omz_dir>/data/dataset_classes/aclnet_53cl.txt. For details about the model, see this paper.

The model input is a segment of PCM audio samples in N, C, 1, L format.

The model output for AclNet is the sound classifier output for the 53 different environmental sound classes from the internal sound database.

Input

Original Model

Audio, name - input, shape - 1, 1, 1, L, format is N, C, 1, L, where:

  • N - batch size
  • C - channel
  • L - number of PCM samples (minimum value is 16000)

Converted Model

Audio, name - input, shape - 1, 1, 1, L, format is N, C, 1, L, where:

  • N - batch size
  • C - channel
  • L - number of PCM samples (minimum value is 16000)

Output

Original Model

Sound classifier (see labels file, <omz_dir>/data/dataset_classes/aclnet_53cl.txt), name - output, shape - 1, 53, output data format is N, C, where:

  • N - batch size
  • C - predicted softmax scores for each class in [0, 1] range

Converted Model

Sound classifier (see labels file, <omz_dir>/data/dataset_classes/aclnet_53cl.txt), name - output, shape - 1, 53, output data format is N, C, where:

  • N - batch size
  • C - predicted softmax scores for each class in [0, 1] range
