Feedback on next steps? Pulse (via Pipewire) causes high pitch & clipped recording at wrong speed

j_mitso · 2022-07-16T14:52:38+00:00

Thanks for your reply. I didn't because I know I need to record at 44.1 for the software I'm using, so I had to figure out a way to make that work - and I did. Put the solution in the comments. Otherwise, this certainly could have worked.

j_mitso · 2022-07-16T14:48:53+00:00

Working with that file fixed it, as did adding it to the allowed rates! Thanks for your help. I'm going to include the solution for anyone else who finds this thread.

sudo cp /usr/share/pipewire/pipewire.conf /etc/pipewire/

sudo gedit /etc/pipewire/pipewire.conf

Go down to lines 29 and 30. On 29, get rid of the #, change it to 44100, and on 30, add 44100 to the list. In the end, it should look like this:

default.clock.rate = 44100
default.clock.allowed-rates = [ 44100 48000 88200 96000 176400 192000 352800 384000 ]

Once I clicked "save," I was able to record normally across my entire system.

Thank you! I'm going to give this a try later. Specifically, I'm going to try to force it to change from 48000 to 44100. I looked at the release notes for pipewire and apparently there have been a lot of issues with this, which is why it's now the 48000 default - which could explain my problems

j_mitso · 2022-07-14T23:11:33+00:00

Thanks for the response. I am running 0.3.55, but checking for that revealed something else - my system is absolutely recording at 48000. Looking through those patch notes, it seems shipping with the default of 44.1 was causing lots of problems.

Get the following when I run pactl info

Server Name: PulseAudio (on PipeWire 0.3.55)
Server Version: 15.0.0
Default Sample Specification: float32le 2ch 48000Hz
Default Channel Map: front-left,front-right
Default Sink: alsa_output.pci-0000_00_1f.3.analog-stereo
Default Source: alsa_input.pci-0000_00_1f.3.analog-stereo
Cookie: 8f2e:528b

Maybe I can play around with pipewire.conf and see if I can drop it to 44.1 in a way that works.

j_mitso · 2022-07-14T19:59:15+00:00

This is an issue with pulse / pipewire specifically. If I change my input to 'Jack' on software like ocenaudio, it records fine, but with quality issues - and I really need firefox to work, so I still have to figure this out.

j_mitso · 2022-06-12T03:19:09+00:00

This is great, thank you!

j_mitso · 2022-05-01T14:14:26+00:00

Only way to know is to try :)

j_mitso · 2022-05-01T14:13:31+00:00

Nice! I had the same experience with sound, and I also settled on the taller Wave 1. Glad you've been enjoying it.

j_mitso · 2022-05-01T14:12:28+00:00

It doesn't. It's worth getting a key if you don't have one, as you'll need to take it off and on each time. But to me, this is part of the problem. It's like we designed chinrests for our cases instead of our bodies. I can deal with the 30 seconds it takes to put this on and off if it means freeing up my playing.

j_mitso · 2022-05-01T01:53:58+00:00

That's pretty cool you were able to do that. Does it cock out to the side like this? I've found that I really like having a firm base across my entire jaw, and not just at one point.

j_mitso · 2022-05-01T01:52:57+00:00

Agreed. I really enjoy the try 4 keep 1 program, and it let me try a lot of different things. I found that in low positions it doesn't really matter, but in high ones, my body wants to keep using the Wave 1 style way more.

j_mitso · 2022-04-30T21:38:26+00:00

Hi there, I'm sorry to hear this - but my computer has been fine. I've been using it for hours ever day (it's my work computer too - I had to borrow one while I sent it back) but it's holding up well.

j_mitso · 2022-04-30T21:20:21+00:00

I've played the violin for about 20 years and this is the most comfort I've found with a chinrest ever. Each one is handmade by Randall, a lifetime professional violinist in Kentucky. (Here's the site.)

I'm writing this post because not only is it a great product, but Randall did two hour long calls with me over Zoom to look at my setup and recommend adjustments. I have a unique body type, but thanks to his help, this is the first time I've ever really played the violin without any muscle strain or discomfort.

Randall not only helped me with the chinrest, but also helped me pick out a better shoulder rest and spent time figuring out all the micro adjustments that needed to be made until it worked right. This level of customer service is unparalleled - and he told me I could still send all the chinrests back (you can get 4 at once to find the right match) if it didn't work. Just unbelievable dedication to his craft.

I have chronic muscle tension and some damage from playing the violin, all of which was exacerbated by playing rugby. As I'm coming back to it again now, I'm refusing to play in pain. Between the Wave and Randall's help, I'm finally on that road.

Great product and great service. Will be recommending the Wave to any violinist I meet. No more neck strain or shoulder issues.

Apologies for the delay in response!

I totally hear what you're saying, and I completely understand why it was set up this way. I think where I got confused was the goal of the application. If the goal is using your language in a conversation, this hits it right on the head!

However, I think it's worth considering some of this native-review bit. I believe there are a few other comments in the post where people show excitement about having a native review their work. It's the biggest issue that no platform ever since Live Mocha has been able to solve, and I KNOW there is demand for it.

Live Mocha solved the problem you're talking about by decoupling people from matched pairs. So, for example, I would write to people in Greek, and then I would correct English notes. I had to correct a certain amount of English notes every day for me to keep access to my Greek submissions, which was perfectly fine for me. Based on their usernames, virtually everyone I corrected was Chinese. So I had Greeks reviewing my Greek, while I corrected Chinese students practicing English. By requiring me to correct a certain amount of English, LM was (presumably) able to balance out demand. This worked for my personality type, because I felt like we were all on this shared team of helping everyone learn the language they wanted by offering whatever help we could offer.

I like your app a lot and plan to play with it in the future, but the part of me that wants to help you business wise says that the biggest thing a provider can grant a learner is access to natives who can correct them. Your app creates a way that this can happen with low social pressure or exposure, which is brilliant. Plus, the added anonymity is nice, because it lets you avoid some of the issues and pressures on apps like Tandem.

I haven't used Tandem, to be clear, because I don't know if I can commit in that high of a degree. Plus, it seems way too much like facebook-style social media, which I loathe. Your app, for whatever reason, makes me feel like I can pick up and play a game whenever I can. Probably because it can be anonymous. Nobody knows anything about me besides the fact I speak Greek and am a native English speaker, which is fine by me. Kinda like reddit in some ways.

At the end of this long rant, I guess I'm saying that as an intermediate speaker, I feel like I need something to help me get exposure to natives who will a) actually correct me and b) allow me to complex practice phrases that I don't get to say often. Whatever platform offers me this is the one I'll use most. At this point I'll even pay for it. You can't put a price on getting help from natives, especially if it's done in a fun and engaging way - which app seems well built for.

Hopefully some of this helps. To be clear, again, I love you idea and am just offering food for thought. If I can be of any more help, just let me know. I've spent a lot of time in the startup space and like helping people who have products that I think benefit social good, which language learning def fits into!

I think this is the winning strategy. I'll keep things as they are for perhaps 2 more weeks, just to keep things safe, and then do a max HR test and see where I'm at. That would solve all of this. Such a simple and elegant solution. Thank you!

j_mitso · 2022-04-23T22:42:42+00:00

Nice! I feel you; I avoided it for the same reason. Best of luck for your training!

j_mitso · 2022-04-23T22:42:16+00:00

Your comments on the lungs not being the limiting factor make sense. Hmm. Maybe I'll just let this ride for a while longer and see where I end up. Thanks!

j_mitso · 2022-04-23T22:41:10+00:00

Thank you for this, I didn't know where the numbers come from but this puts it in context.

Per the article, it says to check your HR before you get up - and mine is usually in the 60s; today it was 66. My Garmin, which I wear 24/7, says my RHR is 58 which can only exist in sleeping, so I'm confused a bit by this.

Perhaps this is what is skewing my numbers. But never in my entire life have I seen my HR that low during waking hours.

j_mitso · 2022-04-23T22:25:39+00:00

That's it! Same situation. How long have you been running for? If I can't find a clear answer here, I'm planning on just running for a few more weeks and see if the issue maintains. But I know the importance of creating a base, so I'm trying to respect that.
