I am looking for something (API, new feature, DSP, hardware) that could achieve the following:
Let’s say the user has a usual volume of -30 dB.
This ‘feature’ would let the user tell the system to go from silence to -30dB in ‘5 seconds, or 3,…) when he hits play after having paused the music. Viceversa for pausing. Same thing for the power on / power.
Any ideas?
Please point me in the right direction
