|---|---|---|
| minute | it just takes some time to print all the labels and everything, the first batch is 350 units | 12:19 |
| minute | _Bnu: do you know why ahi/the driver eats so much cpu just when playing back audio? | 12:20 |
| minute | looks like 48khz 16bit is too slow on Z2 mode in a3000/030 | 12:21 |
| Jadek | minute I'm just asking because someone wrote that he received information on the e-mail about the shipment. And I haven't gotten anything yet. I just wanted to ask. | 12:24 |
| minute | Jadek: it's a process | 12:24 |
| Jadek | minute Ok, thanks for the information. You're doing a great job! | 13:06 |
| _Bnu | Uhhh, because AHI uses a lot of CPU? I guess. | 13:11 |
| _Bnu | Depends on which version you use as well. | 13:11 |
| _Bnu | But like. | 13:11 |
| _Bnu | 48KHz 16-bit is by no means a normal thing to use and expect to have any CPU left over. | 13:11 |
| _Bnu | I typically pick something like 11KHz 8-bit or so. | 13:11 |
| _Bnu | If you can manage to get hardware mixing working, you could handle that on the ZZ9000 instead of on the 68k CPU, but by default AHI does everything itself. | 13:12 |
| _Bnu | Also, AHI 6.0 uses way more CPU than 4.18, but I'm pretty sure I mentioned that already. | 13:13 |
| _Bnu | The PiStorm can handle it, but that's running at an equivalent of a 125MHz 68030, or more if it's on Emu68. | 13:15 |
| minute | _Bnu: ok, understood! i'm using 4.18, and also wrote in the AX manual that we don't recommend 6 | 13:22 |
| minute | _Bnu: i was just thinking, if it would just pipe the audio through, it's only 48000*2*2 bytes per second, i.e. 187.5 kilobytes/s, Z2 should be able to handle that | 13:23 |
| minute | it works fine with Z3 (it just hogs the CPU a *lot*) | 13:23 |
| minute | (a 68030/25) | 13:24 |
| minute | i'm wondering if AHI is trying to do in-place operations on the audio buffer | 13:24 |
| minute | i.e. reading or writing multiple times instead of just copying one big burst | 13:24 |

| _Bnu | AHI is always doing mixing and resampling, yes. | 14:12 |
| _Bnu | You have to tell AHI if you want to do it yourself, but it doesn't appear to work. | 14:12 |
| _Bnu | Toni Wilen said he never got it to work either, so it's like... yep. | 14:12 |
| _Bnu | But even then. | 14:14 |
| _Bnu | You're not in an RTG mode, are you? | 14:14 |
| _Bnu | Because that'll use a lot more bandwidth than anything AHI can do if there's anything updating on the screen. | 14:15 |
| _Bnu | (And Z2 doesn't even have enough bandwidth for 320x200x8 60Hz.) | 14:16 |

| minute | _Bnu: totally in RTG mode ^^ | 14:26 |
| minute | but i can check that, good idea | 14:26 |
