Hi, I am building a skill that plays audio clips.
A problem that I'm running into is that the volume of any given clip may not match the volume of Alexa's speaking voice.
Does anyone have any suggestions for this issue?
Thanks for your question. I'll research to verify if there's a standard "default" volume level for audio files (to match the Alexa voice volume). In the mean time, this information may assist:
Update from our Alexa dev team:
"There are several tools to adjust the base volume of MP3 files. ReplayGain(https://en.wikipedia.org/wiki/ReplayGain ) is a common standard for normalizing volume through MP3 tags, which most playback systems support. In case our playback doesn't support the ReplayGain standard (I can't find documentation on it one way or another), MP3Gain(https://en.wikipedia.org/wiki/MP3Gain ) is a tool which uses the ReplayGain algorithm, but directly modifies the MP3 file's audio data to adjust the volume scale factor on each frame."
