Add export mixdown and user-configurable directories

• Add user prompts for recording and export directories in session setup
• Implement full-song mixdown export with multi-track mixing
• Add ‘E’ key to export all tracks to single stereo WAV file
• Use miniaudio decoder for reading segments during mixdown
• Apply normalization to prevent clipping in mixed output
• Update recording path to use user-specified directory
• Add file/directory helper functions (ensureDir, joinPath, baseName, copyFile)
• Fix ma_decoder_read_pcm_frames call to use 4-arg signature (oh my gosh this was a pain)
• Update function signatures to pass recordDir/exportDir through session flow

I’m planning on adding a live visualiser next for the actual audio aspect of this.
But here’s what I have worked on so far:

• I integrated the recording aspect with the tracks and made it so that you can record and add it to tracks and play it back!
• I did some optimization and spent like 30 minutes fixing a mistake that I made regarding linking C and C++ with a header file and then went into a wikipedia deep dive about function overloading.

I added basic audio functionality (hackatime is being weird and only adding 40 minutes on this devlog, but It’s alright though). This audio functionality just includes a basic test right now and I am yet to link it with the rest of my code and add a way to actually record, I’m 99% sure that’s a job that takes like ~30 minutes just because of how smoothly everything works and how easy the awesome library that I am using is to use. Check out my recent commit on my GitHub for this project to see which library (its really just one header file in the dependencies folder).

I added:

• Basic functionality to the main menu and the actual DAW itself.
• You can make a session (like a project/song) and navigate around the basic interface.
• No recording or actual sound interface yet, it’s just a basic UI that I got going here.
• Sessions don’t actually get stored anywhere, thinking of making a file format for that, so that you can load them in that would be neat.
• You can change basic project settings, but buffer length currently does nothing.
• Exit option works too, it just quits the program (what else would it do).
