Hello,

I have been using the Tapo C840 for my newborn for almost 2 months now and I have some improvement suggestions for one of its features, lullabies:

1. Ability to import lullaby from audio file.

    Currently it is only possible to add new lullabies by recording audio with the phone microphone. Needless to say it's a bit of a dated approach and in need of improvement.

2. Gapless playback.

    Especially for continuously playing ambiental background sound samples such as "white noise" and "sea waves", the existence of a ~1 second gap every 30 seconds (before each repeated playback) is quite bothersome.

    It seems to me it's an optimization problem of the "repeat single" playback mode, as the lullaby seems to be re-loaded from memory everytime instead of the loaded audio stream being reused.
