Currently eliminating the first and fourth quarter of frequency
playFFT takes in a filter, which for now can be created with lowPassFilter
added minimal buggy example
Added methods to plot time-domain and frequency-domain samples in the plotly module.
Added direct conversions between Sound and FrequencyList in sound_fft - Added definition for FrequencyList type. - Added public methods sound_to_frequency and frequency_to_sound for direct conversion between Sound and FrequencyList types. - Copied the functions next_power_of_2 and sound_to_time_samples from sound module into sound_fft module. Hopefully they can be deleted from sound module eventually. - Added sound_fft/sound_functions.ts to allow sound_fft to use some select functions from sound, as there are still issues with importing.
…raw_sound_time_samples_2d
Renamed `draw_sound_frequency_samples_2d` to `draw_sound_frequency_2d`. The new `draw_sound_frequency_2d` takes in a `FrequencyList` instead of `FrequencySamples`, and plots the full graph (up to sample rate) instead of half. Also removed `draw_sound_time_samples_2d`.
…lude frequency range.
Added frequency augmentation
Fixed issue where long sounds cannot be converted to frequencies
Made low_pass_filter and high_pass_filter symmetric
Merge source-academy/modules into Unknown15082/modules
added points limit to plotly sound drawing functions
added documentation to sound_fft and fixed some in plotly

I would like a description of the limitations of the current library used, for example, the 5-second limit on FFTs. What is left on the TODO and an estimated time to completion? |

Description
Created a new modules (sound_fft) for sound processing and analysis.
Modified plotly for visualizing sound in time domain and frequency domain.
Introduced a list of APIs for students to create their own sound filter and apply them to sound.
