I really don’t want to proceed through the whole of the book
No. Don’t do that, either.
You can post a ten second, sample reading to the forum and we can evaluate it.
Read down the blue links. They’re very short.
The little number on the lower left of the audacity window is the sample rate.
That should be 44100, forever. If you’re keeping score, that’s the digital sample rate of an Audio CD. The other common number is 48000. That’s the sound sample rate for video.
Then at the other end, when you’re done reading, correcting, and mastering; File > Export > Export as WAV your chapter or segment to WAV (Microsoft) 16-bit. That’s your Edit Master. Only then File > Export > Export as MP3 to 192 like this.
You can’t change the MP3 once you make it without damage, so don’t lose that WAV file.
There’s ACX rules for file naming and I don’t have those right to hand.
There’s also rules for amount of silence (room tone) at the beginning and end of each chapter, etc. A surprising number of readers miss this.
Recently, ACX advanced several changes to their publication standards and they’re not all digital related. I must be able to buy your book on Amazon as either paper or eBook. It’s much more difficult for fresh Author/Readers to get published now.
ACX used to offer Audition Evaluation Services where they would run a short reading through a complete inspection and offer hints and corrections. Not any more, They do offer a basic, limited, automatic digital evaluation, but it’s a duplicate of the ACX-Check from here on the forum—and ours is much faster.
So no. Don’t just start reading a book. A lot of the safety nets have been removed.
