| apolkosnik[m] | So, it looks like the AHI-Noteplayer is looking for a realtime mode, when Use best audio mode is checked. | 00:52 |
| minute | should be a realtime mode though, weird | 00:53 |
| minute | apolkosnik[m]: do you use the -tw driver version? | 00:54 |
| apolkosnik[m] | yes | 00:54 |
| apolkosnik[m] | it plays much better | 00:54 |
| apolkosnik[m] | I was trying to set up that octamed sound studio earlier, just couldn't find any octamed modules | 00:55 |

| neoman | apolkosnik[m], I got it running with AHI Noteplayer but you have to choose the driver manually | 08:44 |

| minute | here is a testcase for ZZ9000AX, if you have problems with distortion or stuttering (?), you can help me https://www.a1k.org/forum/index.php?threads/83561/page-7#post-1587500 | 12:58 |
| minute | it's in german but i think the list is readable as english | 12:58 |
| minute | i notice that at the beginning in the very high freqs, there's some harmonics that might be clipping hmm. when i turn the volume in songplayer down to 8 they're gone | 13:01 |
| minute | ah yeah, i think it happens in the 24->48 upsampling in zz firmware | 13:05 |
| minute | http://dump.mntmn.com/sweep48.wav this sounds fine | 13:05 |
| minute | _Bnu: do you happen to have something better than this? https://source.mnt.re/amiga/zz9000-firmware/-/blob/master/ZZ9000_proto.sdk/ZZ9000OS/src/ax.c#L513 | 13:13 |

| gdonner | minute: Both files played ok here, on both 24 and 48 Hz AHI settings | 16:17 |
| gdonner | My setting are as follows: | 16:17 |
| gdonner | firmware and drivers v1.10 | 16:17 |
| gdonner | Kickstart 47.102, Workbench 47.3 (OS 3.2.1) | 16:18 |
| gdonner | 68040 (A3640, rev. 3.2, recapped/fixed polarities) | 16:18 |
| gdonner | Only MuFastROM running | 16:18 |
| gdonner | 68040.library v46.4, mmu.library 47.2 | 16:18 |
| gdonner | This is on my A3000 | 16:19 |
| gdonner | Oddly enough, Play16 (from Thomas Wenzel) seems to play the sweep48.wav more accurately than SongPlayer does | 16:19 |
| gdonner | I'll try all the above on my A4000 and report back | 16:20 |
| gdonner | (this is using the -ahi-tw.lha ZZ9000AX.audio file with a reboot) | 16:20 |
| gdonner | there were a few clicks on first play of the sweep24.wav file | 16:21 |
| gdonner | but I believe that's normal | 16:21 |
| apolkosnik[m] | is there a way to quiet the spikes on the startup (when the machine is powered up, then couple of spikes while it's booting up)? | 16:21 |
| gdonner | no distortion, no stuttering | 16:22 |
| gdonner | minute: ok, both files played fine on my A4000/060 as well | 16:42 |
| gdonner | specs: same as the A3000, except A3660 (50 MHz) | 16:43 |
| gdonner | 68060.library v47.1, mmu.library v47.4 | 16:43 |
| gdonner | MuFastROM also running | 16:43 |
| gdonner | hope this helps! and confirmed: Thomas Wenzel's Play16 plays audio better than SongPlayer :) | 16:44 |
| gdonner | (more complete, more detail) | 16:45 |
| minute | oh, play16 | 16:51 |
| minute | apolkosnik[m]: will be in next fw rev | 16:51 |
| minute | gdonner: thank you very much for testing! so it seems to work as designed then on your machine | 16:52 |
| minute | i already know that the resampling (upsampling to 48khz) in the current firmware is not ideal, as it is missing a low pass filter stage | 16:52 |
| minute | so if you play 44.1khz stuff and it is resampled in the card, this will sound sub optimal | 16:53 |
| gdonner | sure--happy to help! | 16:55 |
| gdonner | BTW, thanks for all your work on this (and Thomas W. too) | 16:56 |
| apolkosnik[m] | awesome, thank you! | 16:56 |
| apolkosnik[m] | Hippo is doing much better once I bumped Priority in PS3M settings to +1 | 16:58 |
| minute | aha? | 16:59 |
| minute | what exactly is much better? no more stuttering? (did you have stuttering before)? | 16:59 |
| minute | btw i had to set the AHI volume in hippo to 500 | 16:59 |
| minute | instead of 1000 | 16:59 |
| minute | or it would be distorted | 16:59 |

| _Bnu | minute: My resampling is probably worse, quality-wise. | 19:13 |
| minute | _Bnu: oh, ok? | 19:13 |
| _Bnu | https://github.com/captain-amygdala/pistorm/blob/main/platforms/amiga/ahi/pi_ahi.c#L282-L305 | 19:14 |
| _Bnu | I thought it sounded fine, but others told me it sounded bad, so I ignored it forever...! | 19:15 |
| _Bnu | I was just happy it worked and didn't desynch to hell and beyond, lolb. | 19:15 |
| minute | _Bnu: looks very similar to mine | 19:19 |
| minute | _Bnu: a physicist told me that it might just be missing a low pass filter | 19:19 |
| _Bnu | My idea on how to make it "better" was to render it as a texture, using bilinear filtering or something. | 19:19 |
| _Bnu | Abuse the Pi GPU to smooth out the waves, 16-bit luma. | 19:19 |
| minute | funky | 19:20 |
| _Bnu | I figure you could probably even do some sort of mixing that way, with some alpha channel blender setting. | 19:23 |
| minute | yep | 19:25 |
| Jope | phew, ups didn't tell me that the ax arrived on the 12th :-P | 20:23 |
| Jope | by chance I checked the tracking today and it would have gone back tomorrow | 20:24 |
| Jope | delivering parcels: difficult | 20:24 |
| minute | oh :D | 20:27 |
