Sound samples sound pitched down when imported to Amos
Ok this isn't technically code but it is to do with Amos.
I have the main Double Dragon sound effects ripped from the arcade game and so I converted them into an iff sound file using Goldwave and set the sample rate at 22000Hz as I think the max the Amiga can handle is 28000Hz or something. Playback in Goldwave as an iff is fine, but when I import the sound effect to Amos they appear to be pitched shifted down quite a lot and Amos won't let me pitch up past 32000Hz. Am I forgetting to do something? |

Only an ECS Amiga can play such high rate samples. AMOS was coded for OCS mostly so that feature is likely unsupported.
Try a lower sampling rate. Sent from my Prism II using Tapatalk |

Thanks for the reply.
Ok I tried it at 16000Hz and when I sample up within Amos it sounds a bit closer to how it should. However, the sample itself seems to have been cut off about halfway through in the Amos sampler when I import it. EDIT: I exported it at 8000Hz and I can now pitch it up to near perfect level, but it's still only loading the first half of the sample. Last edited by Brick Nash; 23 September 2017 at 18:00. |

Is the sample longer than 128k?

They might be. I'll admit it's not something I was aware of. I did find a workaround in that I imported the iffs to Protracker, upsampled and then saved before importing into Amos where the whole sample was available. There was a big pop which appeared at the start of the samples after saving in the bank, but some trimming saw to that and they were good to go.
Amos is a funny little program sometimes, but I still love it. Anyway, thanks for the info. I'll add it to my ever growing book of "things to check". I don't know where I'd be without you guys on the forum, so thanks again. |
