This working space needs to be 256 slots long.\n\n## License\n\nDo whatever you want with this code, just don't blame me. :)  Bug reports appreciated.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeraintluff%2Fjsfx-fft-big","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgeraintluff%2Fjsfx-fft-big","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeraintluff%2Fjsfx-fft-big/lists"}
