Hi,
I have been working on a conference solution based on a smartphone grid. Right now, I am stuck on Android Smartphones, where although I have managed to normalize loudness programmatically when it gets played on different phones then, due to the Hardware difference of speakers, it plays with different loudness.
I am keen to know if there is any way to make it sound the same on different Android Smartphones concerning loudness.
I am using DRC (dynamic range compressor with gain) to normalize it on specific dBs. But still, it sounds different on different smartphones in terms of loudness.
Regards,
Khubaib
You can try to measure each phone's volume(in dB) with its microphone before playing the sounds. And adjust them one by one before playing sounds.
Hi Ivan Drankov, On android, there are multiple modes in which audio is recorded. The method I am using is VOICE_COMM which processes audio with the following algorithms:
1. AEC
2. NS
3. AGC
With these algorithms, I can't get the audio through the microphone; the phone's speaker is playing.
Khubaib Ahmad You can try to use an external microphone to calibrate them one by one then and log the settings into database.
Ivan Drankov Okay, let me try that. But I need more real-time resolution
