Multispecies Whale Detection
Overview :
Multispecies-whale-detection is an open-source project developed by Google, aimed at detecting and classifying whale sounds across different species and geographic regions through neural networks. This tool helps researchers and conservation organizations better understand and protect marine biodiversity.
Target Users :
The target audience includes marine biologists, ecologists, and machine learning researchers. This tool aids them in more effectively identifying and studying whale vocalizations, enhancing the understanding of whale behaviors and ecological environments.
Use Cases
Marine biologists use this tool to study the vocal characteristics of specific whale populations.
Conservation organizations utilize this tool to monitor whale migration patterns and activity areas.
Educators use this tool to demonstrate the diversity and complexity of whale sounds to students.
Features
Create training input: Generate training input from labeled audio file collections through the Beam pipeline.
Handle various audio formats: Support multiple audio file formats.
Audio file processing: Split multi-channel files and resample to a common sampling rate.
Audio clipping: Segment large files into shorter clips suitable for training.
Label and metadata merging: Merge labels and metadata with audio files, represented as TensorFlow Examples features in output.
Adjust label start times: Align label start times relative to the beginning of each audio clip.
Record serialization: Serialize merged records into tensorflow.Example format.
How to Use
1. Clone or download the multispecies-whale-detection project.
2. Install necessary dependencies, such as Apache Beam.
3. Prepare audio files and CSV label files.
4. Use the examplegen tool to generate training data.
5. Train a neural network model using the generated training data.
6. Utilize the trained model for detecting and classifying whale sounds.
7. Analyze the model outputs to extract features and behavioral information of whale sounds.

Vocal Remover
This free online app helps remove vocals from songs by creating karaoke versions. Once you choose a song, the AI will isolate the vocals from the instrumental track. You'll get two audio tracks - a karaoke version of your song (without vocals) and an a cappella version (instrumental-free vocals only). Despite the complexity and high cost involved, this service is completely free to use. Processing typically takes around 10 seconds.
