The learning curve is STEEP because there's SO much that Reaper can do, and it's NOT geared for audiobook recording, it's built for SO MUCH MORE. I found Reaper and it blew my mind - I couldn't figure out up from down - didn't even know where to start because I hadn't used a DAW before. I was using Audacity initially, then went searching online for a better DAW. I too had issues trying to measure the -18 to -23 dB RMS levels.
I too had a lot of questions about getting my audio files to ACX requirements. Since you're in the Reaper site, I'm thinking you're using Reaper.
So I guess I will have to do some homework. *Also another bigger challenge I ran into was when I exported these wav files to mp3s (File-export-export as MP3) (that's another ACX requirement) and then ran an ACX check, the Peak levels and RMS levels failed miserably all 3 times. *Why such a big change in the noise floor with the audacity effects? I ran an ACX Check in audacity on the same file as a 24 bit WAV (after adding a little bit of compression with a threshold at -15dB and ratio of 2:1 on my raw file in reaper but this time without the audacity effects of filter curve, loudness normalization and limiter) Noise floor: -88.03 (Pass - barely I would think, phew) I ran an ACX Check in audacity on the same file as a 24 bit WAV (after adding a little bit of compression with a threshold at -15dB and ratio of 2:1 on my raw file in reaper and also including the audacity effects of filter curve, loudness normalization and limiter) Noise floor: -90.21 warning (too low - dead silence sounds unnatural) When I rendered my raw recording as 16 bit WAV (as per audacity instructions and also ran the various effects of filter curve, loudness normalization and limiter and the ACX check) So tried both your suggestions.hence taken me so long to reply. There is stuff more for musicians.Ĭan someone suggest how I can adjust the peak levels without affecting the RMS level or how I can adjust the RMS levels without affecting the peak levels? I have read several forums but not much help out there for audiobook producers. If the Peak level passes the RMS level fails or vice versa, I have even tried adjusting the volume slider in item properties.
Yet another at a slightly different gain: I have run my mp3s against the ACX check on Audacity. Some of ACXs submission requirements are: I have also recorded a couple of tracks about 1 - 1.5 mins long, each time with a slightly different gain. I have spent some time trying to understand reaper. So, I guess a newbie to the world of audiobook productions also. I am a newbie on Reaper and am hoping to produce audiobooks for ACX.
