Creating an Audio File Player from scratch
There is a cross-platform audio library for Rust: cpal https://github.com/rustaudio/cpal

Read the voice from the microphone for accessibility
cpal crate should work fine for this use case, though it might be unnecessarily low-level for your use case.

Modify pitch and volume while a sound file is playing
I had to do something similar to this a while back. I used cpal.

What’s everyone working on this week (including AoC, 51/2021)?
Working on a live performance software that would let our band have live real-time practices over the internet. Top priority is minimum latency, so I'm trying to hook it up through ASIO. Not much luck yet. I've tried cpal, but I've run into numerous known random bugs (and some versions don't compile for me). At least I confirmed that I can push the audio through a TCP socket successfully.

How to read out decibels from default audio input device?
With https://github.com/RustAudio/cpal you can access the microphone in a cross platform way, but you’ll get values of range [-1,1] out only. To calculate absolute decibels you would need to calibrate for your specific microphone with a known source.

Hey Rustaceans! Got an easy question? Ask here (7/2021)!
you need to use a "loopback" device, as shown here - https://github.com/RustAudio/cpal/pull/478 (note, ive only tested this on windows - if its not supported on linux you could always plug your sound card output into its line-in/mic jack)

Symphonia v0.5.2: Audio decoding in safe Rust, now often faster than FFmpeg!
Regarding improving the API for 0.6, something that bugs me about the current Rust audio ecosystem is that everyone is reinventing the wheel with their own audio buffer types each with their own API that downstream users have to learn. This makes it more of a hassle to pass audio data from one library to another than it should be. I've been contributing to the audio crate which provides buffer structs and traits for working with audio buffers with a common API regardless of their layout in memory. I have a work-in-progress branch for Rubato refactoring it to use the audio crate, though there's a bit more work to do in the audio crate to complete that. Would you be interested in using the audio crate in Symphonia?

Modify pitch and volume while a sound file is playing
If you want to change tempo and pitch together, that's resampling. You can use Rubato's asynchronous resamplers for that.
What are some alternatives?
When comparing cpal and rubato you can also consider the following projects:
