Here's a little expression that strips off any trailing ".<extension>" from $1 and tacks on ".wav". "${1%.*}.wav" Look under "Parameter Expansion" in bash(1) for how this works. Note that some of the constructions there are bash-specific; you can compare with "Parameter Expansion in dash(1) to get the portable subset.
