Release V1.2

Ez pz replacing audio

In this release:
Audio conversion is improved (I wish I could take credit but chatgpt dunnit...)
You can enter the 'recorded at' and 'current speed' flags to update those in the file now
If your song starts abruptly there seems to be an issue where it begins very loud, try to add the slightest amount of silence at the beginning to avoid this. Hope to fix automatically soon!
