Uncompressed audio format for continuous recording...

[mediawiz]

I am trying to find an uncompressed audio file format that I can use to continuously record audio to (efficiently).

The audio file formats that I have come across so far require info to be continuously updated in the files header (header chunk), as the data is written to the file.

I am looking for an audio file format that allows me to just write basic audio format info to the header (ie: bits per sample, number of audio channels, etc...), and then just coontinuously append the sample data to the end of the file (without having to go back and update the header).

Having the disk file system continuously fo back to the start of the file to update the header causes serious perfomance issues.

Suggestions?
