Hi all. I am hoping to describe the process I am trying to achieve, so that suggestions of how to achieve it will give me the necessary leads. Man, Help and Docs assume a prior specific knowledge; if only on what tools to read about. My objective is to:- 1> convert and stream a collection of .mp3s sequentially into a single .wav and hopefully, normalise to a lower volume level in the process. 2> having done the first step into a pair of long .wav's; to them stream both in parallel or mix them into a third single .wav... maybe even a long single mp3 but that can be done as an additional later step if necessary. The key bits are - to sequence a collection into a single entity, normalise such an entity, then mix a pair of such entities into a third single blend. For those really interested, I have to put backing music to a lot of verbalised text. Any thoughts please?
