Converting a library of audiobooks for blind people

Postby kbaerwald » Sun Mar 04, 2018 2:58 pm

Hi

I try to setup a reasonable process for converting a library of audiobooks for blind people to a condensed mp3-based library. The typical audiobook contains 10-15 single mp3 files previously converted from the original analog Compact Cassettes. My idea is to convert all mp3 files to wav, merge the wav files to one wav file containing the whole audiobook (with cue marks) and load it into Goldwave for further processing. This is to trim the technical (spoken) information at the beginning and end of that file, remove the worst analog noise and save the resulting file as flac for further tagging and processing.

The first problem I ran into was the size of the merged wav file - up to 6GB (16bit data). I can merge into such a file with Goldwave merge function but it does not load due to time length problems. If I tell the merger to save a flac file instead it takes nearly 20 min for a typical audiobook - much too long. I have a Core i7 4720HQ system with 1TB SSD and 16GB memory and expected this step to be much faster. Furthermore - after the merge Goldwave does not load the generated flac file into the workspace automatically: it just merges and then I have to load the merged file manually which again takes time as Goldwave has to decode the flac again.

Before I cannot solve these problems I will not continue with my other tasks.

Does anybody here has a good idea how to avoid these obstacles? Maybe they are selfmade :( ? Should I change my work flow? Thanks for any hints

I am really perplexed as th WHY you would want to convert MP3 VOICE files to WAV. ?!?!? You did say Audio Books, correct? Mostly Voice? Voice files don't need that much "fidelity". I have taken audio CDs and converted them to MP3s using GoldWave many times. I do that to place all the CDs onto ONE CD, so my wife can listen to books in her car - WITHOUT having to fumble changing the CDs out periodically. I have placed as many as 35 CDs onto one CD by reducing the storage down to 48 Kbps. YOU may not wish to go that low, but most people will not be able to tell the difference.

You could save the files in "Extended Audio (*.xac)" format. That is an uncompressed format that can store very large files. There is no decompression time to open a file (the file opens instantly). It's a good intermediate format if you have lots of storage space and want to save time (and preserve quality).
