If you want digital recording with hi quality - well, ALU has policy that - it costs.
4-5 VGs / year could not cost you a lot.
If you got a problem to find a partner/ engenierr who will do it under $100/100EURO contact me on PM
But to be honest, AlcatelAudioStation is a tool with >3000 Euro WPL price, so work with this tool, it's to be expected as 'not free'.
It's good that you are a clever guy, spent some time, gues how to calculate CRC in WAVE and - make a free tool.
But, is your time worth price of convertig 5 VGs ?
