New Poor Quality Recording Fm Radio And Recording Calls

[locutor32]

Good afternoon everyone.

I have checked that the recordings of Radio Fm and calls have a very poor sound quality. For example, the quality of a recording made in the Radio Fm application is:

Format : MPEG Audio
File size : 247 KiB
Duration : 1 min
Overall bit rate mode : Constant
Overall bit rate : 32.0 kb/s

Audio
Format : MPEG Audio
Format version : Version 2
Format profile : Layer 3
Duration : 1 min
Bit rate mode : Constant
Bit rate : 32.0 kb/s
Channel(s) : 1 channel
Sampling rate : 22.05 kHz
Compression mode : Lossy
Stream size : 247 KiB (100%)


In the recording of calls the quality is worse than in the one of Radio Fm:

Format : MPEG Audio
File size : 1.04 MiB
Duration : 9 min
Overall bit rate mode : Constant
Overall bit rate : 16.0 kb/s

Audio
Format : MPEG Audio
Format version : Version 2
Format profile : Layer 3
Duration : 9 min
Bit rate mode : Constant
Bit rate : 16.0 kb/s
Channel(s) : 1 channel
Sampling rate : 16.0 kHz
Compression mode : Lossy
Stream size : 1.04 MiB (100%)


Is there any option to increase the quality of the recordings?

By the way, is there any option to activate RDS on Radio Fm in the MIUI rom?

Thank you very much to all.
