The encoder doesn't support frequencies aside from 44100

Bug Report

Overview

The encoder only supports encoding an AudioClip with a frequency of 44100 Hz. When using a different frequency, the resulting audio file's length will be proportionally affected based on the ratio of 44100 to the selected frequency. For example, if the chosen frequency is 16000 Hz and the original recorded audio is 30 seconds long, the encoded OGG file will have an approximate duration of 82 seconds (44100 / 16000 * 30).

To Reproduce

Steps to reproduce the behavior:

• Record an audio using the unity's Microphone api and set the frequency parameter to 16000
• Convert the captured audio to bytes using the EncodeToOggVorbis method
• Write the bytes to disk and view the length of the recording File.WriteAllBytes(Application.persistentDataPath + "/test_audio.ogg", oggData); and check the audio length and quality

Expected behavior

Resulting audio should be equal in size to the orignal recorded audio without sounding "slowed down" or distorted

Additional context

This package uses this nuget package and has the same compatibility per table:

I've tested this out with 16000, 24000, and 44100.

I think the problem lies in how you're setting the microphone parameters. Unity's microphone implementation is notoriously broken tbh, which is why I provide these audio libraries as a means to mitigate that problem.

I'd like to see a better example of your usage to properly suggest changes to get the desired result.

Also I wouldn't recommend this package bc the base nuget package it is based on is also flawed. Better to use the wav encoder package IMHO.
