Audio Tagging
Introduction
Audio tagging is the task of labelling an audio clip with one or more labels or tags, includeing music tagging, acoustic scene classification, audio event classification, etc.
This demo is an implementation to tag an audio file with 527 AudioSet labels. It can be done by a single command or a few lines in python using PaddleSpeech
.
Usage
1. Installation
pip install paddlespeech
2. Prepare Input File
Input of this demo should be a WAV file(.wav
).
Here are sample files for this demo that can be downloaded:
wget https://paddlespeech.bj.bcebos.com/PaddleAudio/cat.wav https://paddlespeech.bj.bcebos.com/PaddleAudio/dog.wav
3. Usage
-
Command Line(Recommended)
paddlespeech cls --input ./cat.wav --topk 10
Usage:
paddlespeech cls --help
Arguments:
input
(required): Audio file to tag.model
: Model type of tagging task. Default:panns_cnn14
.config
: Config of tagging task. Use pretrained model when it is None. Default:None
.ckpt_path
: Model checkpoint. Use pretrained model when it is None. Default:None
.label_file
: Label file of tagging task. Use audioset labels when it is None. Default:None
.topk
: Show topk tagging labels of result. Default:1
.device
: Choose device to execute model inference. Default: default device of paddlepaddle in current environment.
