20:59:11pamaurylebellium: do you have a way of recording the output of your A10 with a computer ?
21:03:27johnb3pamaury: do you want this with the OF or your RB port?
21:06:33 Quit foo|sh (Ping timeout: 240 seconds)
21:10:26pamauryany should do
21:11:10johnb3I have the the A25. Would that do?
21:11:22 Join foolsh [0] (
21:11:54pamauryyes that should do
21:12:30johnb3Then I can do thist tomorrow. Any particular music or just a sine wave?
21:14:07pamauryjohnb3: use a sine wave (for example and do the following:
21:14:07pamauryplay the sine way in repeat on mode. Then start with the highest possible volume and gradually decrease the volume (leave each volume step for a few seconds) until you reach 0. Then send me the recording
21:15:13pamauryyou should make sure that the recording volume is such that at the highest volume on the player, you are around 80% of the recording level
21:15:42johnb3Ok, I will do this tomorrow morning.
21:18:45pamauryI expect the A10 and A20 have the same volume curve but that will a test to my theory if we cn have lebellium do the same
21:18:59lebelliumA10 and A20 are the same
21:20:08lebelliumI'm in vacations this week. I do have time but not necessarily the stuff to record
21:20:16lebelliumI brought the A10 with me though :)
21:20:43lebelliumI left the A20 at home
21:21:09pamauryI need proper recording, otherwise it's impossible to get proper sound levels
21:21:20 Join paulk-collins [0] (
21:22:03pamauryI think the best approach to volume management is to know the volume curve for each player, and then adjust the pcm volume to fill the gaps. I believe the sound curve is essentially the same for each codec, so that's only a few of them
21:22:24pamaurybut I couldn't find the A10 by disassembly, it's too complicated
21:22:40lebelliumlooks like johnb3 can do it properly. I suggest using his recording for both A10 and A20. When I'm back home next week, I can compare and confirm you that volume is 100% identical on both players
21:23:30pamaurywhat matters is less the volume than how it decreases (ie how many dB you loose per step)
21:24:00pamauryon E580 the curve is like this: 3dB/step from step 0 to 10, then 2dB for another 10 steps, then 1dB/step
21:24:09johnb3Ok, you got me curious. I will do it right now.
21:24:22pamauryon older players (maybe E450, not sure), there are actually 100 steps
21:24:41lebellium100 steps in OF?!
21:24:52pamaurymaybe not in OF but in driver yes
21:25:03pamauryon A10 there are only 30 steps (compared to 31) but I don't know how they vary
21:25:31lebelliumthere are 31 steps on E580?
21:25:41pamauryyes, both OF and driver
21:25:59pamaury(at least driver, but I think OF has 30 steps too)
21:26:32lebelliumfrom what I can recally, Sony always used 30 steps in OF
21:26:46lebelliumeven in very old players
21:27:36lebelliumSamsung too. 30 steps to be like an agreement somehow
21:27:58pamaurywell at that point I don't really care what the OF does anyway. What matters is this relate to dB
21:28:04pamaury*how this

21:48:18pamauryjohnb3: your recording is a bit noisy but hopefully I still get something out of it
21:48:30johnb2Strange enough, at full volume it doesn't really look like a sine.
21:49:01johnb2Although audacity doesn't indicate any clipping.
21:49:38pamauryyeah this is very puzzling
21:50:27pamaurythere must be some clipping in the device audio path
21:50:34johnb2I can give it another try at my desktop computer.
21:51:38pamauryjohnb3: could you retry the high volume steps with another sine with much lower volume (ie set sine should have around 30% of the maximum volume in the file)
21:52:24pamaurythere is clearing some clipping => the first 6/7 steps have a lot of harmonic
21:52:36pamaurybut starting from step 8, the spectrum is very clear, with one peakk
21:54:42pamaurythe sound curve looks very similar: 1dB/step for highest 10 steps, then 2dB/step then 3dB/step
21:59:38johnb2the wave form doesn't improve on my laptop even after setting rec volume to the lowest volume in audacity and turning any windows amplificatin off.
21:59:47johnb2I will go to my pc.
22:01:05pamauryjohnb3: I think it's internal clipping, that's why I think using a sine with lower volume (in the file) should fix the problem
22:01:23pamauryin any case, I can't help but notice that Sony massively screws up its volume curves
22:01:30 Join WilliamC [0] (
22:01:37pamauryseriously what the use of a player if 1/3 of the volume step cause clipping??
22:02:03pamauryespecially on something like A10 which is supposed to be high-end
22:04:24 Quit _mt_ (Ping timeout: 255 seconds)
22:09:45lebelliumWM1 is also high-end. Are they both high-end with €1000 difference? :D
22:13:49pamaurylebellium: the high-endness clips as prices increases ;)
22:15:14lebelliumI think the volume curve may also be different with a capped vs uncapped device
22:15:40pamauryit's possible the absolute volume changes, but I hope/believe the shape of the curve doesn't, ie it's only shifted
22:16:01pamaurybut this will need some checking
22:16:26pamauryin any case, with that in mind I could use both driver volume and pcm volume to have an extended range with dB precision
22:16:53johnb2I reduce the amplitude of the sine, now it looks much better.
22:16:54pamaury(up to a constant dB shift that we can ignore)
22:17:56johnb2btw, I used your tool to remove the volume cap of the A20 (or the notificatin part of it).
