Brainstorming in Audio DSP: Time stretching

I am looking for someone who can discuss with me for a few hours in order to set a correct direction for an audio time stretching algorithm. No coding, just brainstorming: frequency domain, time domain, mixed strategy. Matlab knowledge is welcome but not necessary. Upon bidding, it is mandatory for the freelancer to include a presentation - a few sentences that convince me that he/she is well matched to the job specifications. No offer shall be considered if missing this self-presentation. Thank you for bidding.
