I hope it belongs in this category:

I am looking for an audio editor that accepts text files with 32-bit single precision floats as input (they represent waveforms), so that I can then save them unaltered as .wav files. I don't want to program a tool that converts a text file into raw data, so if anyone already had this issue, please tell me what tools you used to solve it.

 

I would use sox, the commandline audio processor. I use it a lot, fantastic quality and faster than any UI-based editor I know. It's available on both Mac and Windows.

From the sox man page:

.dat Text Data files. These files contain a textual representation of
the sample data. There is one line at the beginning that contains the
sample rate. Subsequent lines contain two numeric data items: the time
since the beginning of the first sample and the sample value. Values are
normalized so that the maximum and minimum are 1 and -1. This file
format can be used to create data files for external programs such as
FFT analysers or graph routines. SoX can also convert a file in this
format back into one of the other file formats.

 

Myriad can do the job aswell.

 

Thank you both. Since I don't have a Mac I used SoX. Converting the text to the dat format was a breeze and SoX did a fine job. I didn't even know of its existence. Thanks once again!
