SoX or QtMultimedia?

[scroverty]

Hello!

I'm working with several audio files, and would need to do these task:

• Merge audio.
• Detect Silences (e.g lower than some dB would be considered silences ..)
• Add Silences.
• Fasten/Slow down audios to Fit some miliseconds (Near-accurate needed).

So, should QtMultimedia in Qt5 be capable of solving them all, or should I include libSoX to see those task done?

Big thanks to anyone reply!
