Addition of more audio metrics

[SkafteNicki]

🚀 Feature

Motivation

Feedback based on the newly release audio package (https://twitter.com/ai_rishikesh/status/1412707569710166019), here are a couple of other audio metrics it would be great if we added:

• PESQ (https://en.wikipedia.org/wiki/Perceptual_Evaluation_of_Speech_Quality)
• STOI (https://ieeexplore.ieee.org/document/5495701)
• MCD (https://github.com/MattShannon/mcd)

PESQ and STOI are in plan. The PESQ is limited by its copy right owner. And seems we cannot translate its c++ code to pytorch see here.

PESQ refs: https://github.com/vBaiCai/python-pesq, https://github.com/ludlows/python-pesq, https://github.com/aliutkus/speechmetrics
STOI refs: https://github.com/mpariente/pystoi, https://github.com/mpariente/pytorch_stoi, https://github.com/aliutkus/speechmetrics

Is it good to use pytorch to wrap the c++ implementation of PESQ, like other PESQ implementations?

@Borda can you help with answering what to do here? They use MIT license but they are against replications

[Borda]

according to their statement, we cannot use even modified their code... :/
I guess the only way would be to integrate it as dependency or ask @vBaiCai @SKb10 if they are willing to contribute to TM

I checked the speechmetric implementation...
It uses the two implementation as dependency......

This might be the only way...

Sorry, I forgot our disscussion here... @Borda
I closed my pull request of pesq... and I have invited ludlows to do this job.

Can you give an invitation to mpariente for stoi? His stoi is widely used in audio community. @Borda @SkafteNicki

As for MCD, I am not familiar with it. You can invite the owner of MCD package (https://github.com/MattShannon/mcd).
