yes old thread and slightly off topic.
Going to guess your client does not have a SD card reader that is "High-Capacity" capable. Get them a copy of this recording on low density media then give it to them.
So there is nothing wrong with your wav file. Problem lies with the hardware being used on their end.
This is what tipped me off "gave it to him & the card will not recognize in his either of his readers going to his mac".
That tells me the wav file on that card is not where the problem lies. Their computer cannot read the memory card you gave them. That is your issue.
Next person!
i know this is an old topic, but how is this fix wav supposed to work? i recorded audio for a client on a sandisk 4gb sdhc card on r09 16/44.1, gave it to him & the card will not recognize in his either of his readers going to his mac. is there an easy fix to tell him to try?
