I recorded my self playing piano. I've been reading a lot about the subject and I know I can improve the quality of my recording by applying some filter like compression.
Are there other filters that may improve piano or piano and other instruments?
Is compression really a good idea? I am playing classical so the range of notes and the strength can be very wide. As far as I understand compression will homogenize the sound. Will I loose details?
What else can I do to improve the sound after the recording?
Are there any good online guides about this?
