[Q] Sound "hacks", possible or not?

Hello.
The Motorola Defy, when used with PowerAMP, seems to sound reasonably good.
But... when you adjust PowerAMP's preamp and the EQ and get the volume to sound a lot higher than what you get with the stock player/media effects ... some songs sound distorted.
On the other hand... I've read about the Samsung Galaxy S and it's apps "Voodoo Sound" and "Galaxy Tuner".
Those apps seem to manipulate the hardware directly (instead of software preamp & EQ like PowerAMP seems to do). Apparently the Samsung has a dedicated Wolfson audio chip, so I suppose that's why they can do all of that.
So... the question is... can something of this be applied to a Motorola Defy? Even if it doesn't have any dedicated sound chip, could the hardware be manipulated in some way to achive something like what the Samsung apps do ?
I'm also remembering some mp3 players that could deliver more volume, but due to local european laws were forced to lower their output power... and then some people hacked the firmware and "erased" this limitation.
What I would like is, basically, more power, more volume thru the earphones. Could this be possible for the Motorola Defy ?

A side-note..
I am always curious when someone wants to have their media player louder:
Why?
Have you messed up your hearing somehow? Don't you use earplugs or headphones? Do you listen to music in very noisy environments... while vacuum cleaning perhaps?
That said, perhaps you could be a bit more specific as to what the applications for the Galaxy do exactly if you want to mimic their functionality on the Defy.

I think he's refering to hacks that adjust the frequency respon or/and adjust the software directly tied to the hardware for a more hi-fi experience. Not just meaning getting higher volume or changing eq-settings.
Just googled real quick and come cross this:

I don't know of any mods/hacks but PowerAMP is able to play flac files.

Cyanogenmod includes a dsp app.
It has equalizer etc. pp.
You can also use it on other roms with root, afaik... (had it on hd2 sense rom) just google.

I wan't my music played louder because... I wan't it played louder.
OK, I'll explain it to satisfy your curiosity
I usually play music when I'm working in loud or busy environments and I need to "focus" (intended pun, as I'm a photographer). I can't use canal earphones, so I sometimes need to use higher volume levels... wich the Defy doesn't seem to have, or at least not without distortion/clipping.
Regarding being more specific... don't you find specific enough the names of the 2 apps I've already given ?
Voodoo Sound
Galaxy Tuner
They work together and can adjust the Galaxy's headphone amplifier analog gain, thus increasing the volume noticiably without distortion, or so it seems.
These programs adjust some parameters in the Galaxy's audio chip, so the quality of the resulting sound is apparently better than waht you get from software EQ.
You can find a more complete explanation about all the possibilities here:
galaxyroot.com/guide-how-to-set-voodoo-sound-and-galaxy-tuner
(can't post links yet)
I can live with Defy's audio quality, but I'd want to prevent the distortion and the clipping I get when using PowerAMP to increase the volume.

Exactly that. I want to know If it is possible to do that (or something close to that) with Defy's audio hardware.

The DSP app makes software adjustments. It can't prevent clipping or distortion... it can do a better job than PowerAMP, at best, though I really doubt that.
--------
In short: I wan't to know if it's possible to adjust parameters of the Defy's audio hardware to improve the sound. What "normal" audio apps do is simply adjust the audio data via software manipulation, but they're bounded by what the hardware allows.
I want to tweak the hardware (or, better said, the software that the hardware runs internally)

So... the "developers" part of this forum is just a wish... nobody knows a word about this ?

[Q] Sound issues and question

Riddle me this: how is it that an application like "Lookout Mobile Security" can make my phone scream with a loud volume but when I go to play some media or music on my Nexus it is so soft? What is "Lookout..." doing that no other app can replicate in getting a decent volume?

You must remember, its playing a sound designed to be loud and heard, not a low quality song.

I have noticed when I first got my GN that the speaker volume was pretty weak for videos/youtube/music... whatever really. I use high quality mp3 (320 bit rate) for all my music btw.
There are some apps to help with this of course.
1) Volume+ works great and would fix your problems of low volume alone.
2) If you're really into modding your phone. franco.Kernel Also has options to increase volume and improve sound quality.
I use both of them and the sound quality on my GN speakers is what I prefer now. Sounds great. I know it sucks to have to buy apps to improve something that should be granted out of the box for such a high end phone but it is what it is.

All Galaxy Nexus kernels have sound boost in them.

I do have volume + (free) and it does nothing I can tell, to enhance the sound,,, but If I purchase the app, you say there is a difference?

Volume+ definitely works with the paid version. Or I just use equalizer which works and is free.

I have the paid one, so I can't speak to the free one. I just set the speaker volume to +10 on my GN and it sounds really stronger then stock.
Also description on Free:
A Cyanogen Mod 7 or MIUI ROM is HIGHLY recommended. Running this app on a Stock ROM/Kernel may result in it not working, being far too quiet, or getting even quieter. PLEASE don't comment or rate badly if you are on a Stock ROM as this is most likely the problem.
Thanks.

I have noticed the newer AOKP builds 37/38/39 have much louder sound. Not sure if it is the AOKP Build or the new version of Lean Kernel, but I did notice my alarm is much louder than before.

I want to fix the speakers

Upon using this device for few days, I found out how bad the speakers sound. The highs are extremely muffled out. I also found why it sounds this bad. There is a significant bass boost effect already applied, and you can't un-bass-boost it. You can check this in the equalizer settings in Google Play Music. In fact, after I messed around in the eq app I downloaded, turning the highs way up, it sounds significantly better. But still, it can't give the same effect as reverting the bass boost effect. That's why I want to know if there is a way to override the factory settings and revert back the bass boost effect. And yes, I don't mind the root methods.

Try V4A?

Hey there, we're going to make some audio adjustments so sound should be a markedly better.

When should I expect this update?

Very keen to know when this will be released as well. Just using basic notification sounds, I get dreadful 'hissing' as the sound file tails off. Its really bad. Vibrates like crazy watching videos. It's definitely over eq'd and/or too much gain.

Is that gonna be a software update?

Right now, we're not sure if this audio tuning will make our next MR update, but indeed it is a software update that can help with the audio.

It's been a month. Do you guys have a plan for the next update?

I'm also excited for the next update. Sounds like you guys are fixing all my issues at once (camera, speakers, and heat). Basically waiting for that before I sell off my nexus 6p.

Received the update! It's freaking amazing how much the speakers and the sound output has improved. Didn't expect this much of improvement. Thanks guys!

Yeah I hope so too. I use an eq app to turn the volume down. Also is it just me that the left and the right channel of the audio switches for a split second randomly?

Does anyone here have a successfully working plan for Viper on Robin? I've ended up having to adjust the CPU through Kernel Adiutor in order to eliminate crackling/popping while on ViperAtmos Stock 4.7. I just want this phone to sound great. Otherwise, it's perfect. Thank You!

What adjustments did you make? When playing music and screen turns off music stutters horribly. Unbearable.

Hi-Res output Snapdragon 625

Tested on the lousy zenfone 3 zoom (stock 3.5mm audio sucks inspite of DAC chip because of the poor engine optimization) and it worked like a champ but i believe other devices with SN 625 may benefit from it and they are A LOT, (use 709 build ONLY) other builds won't work as good, i tested them all.
Please do make a feedback on which other device this worked.
Snapdragon 845 devices (e.g. Sony XZ2) – improved Hi-Res Output detection
Sony XZ/XZ1 – improved Hi-Res Output detection
Lenovo X3 – reenabled 24bits
OnePlus (1st edition) – disabled DVC for Hi-Res output due to forced speaker playback
added new per-output option – No Duck – for cases when notification causes issues. Activated by default for Hi-Res output for some Snapdragon 625 devices (Asus Zenfone 3)
HTCs @ 7.0 – improved Hi-Res Output stability
Nexus 6P – fixed notification coloring
Enjoy Hi-Res music all.

Direct download, use poweramp unlocker to activate it.

Did you toggle the 'Wired headset/AUX" ? and was your test with headphones or via the loud speaker? and what your headphones are?
This release 709 worked for me gloriously! the only problem that it's not free and needs some work that you can find on youtube or i would post a fellow up about the odds of activating it but i just needed a conformation that it at least made a difference by utilizing the DAC chip on board!!

I've downloaded the apk you uploaded and followed the screenshots. It made zero difference to the sound quality. Poweramp DVC is great on other devices, but on my zenfone it sucks, the audio is distorted, the only way to tolerate the audio quality is by disabling it. Best player I could find so far for my zenfone is Phonograph.

The zenfone 3 zoom have an amazing sound quality and believe me the bass is insane via a good headphones, you just need to find a solution to make use of it's potentials, if you want to go throw troubleshooting provide some more information like the exact model and what software build you are currently running... you are right about the distortion i was very upset with the sound quality at the beginning but poweramp made the DAC work properly.

I wouldn't say that the sound quality on the zenfone 3 zoom is amazing. This DTS audio thing is terrible and makes sound awful. I've installed an even older version of poweramp and tried your solution, and it made a difference with my JBL T210 (not the best one around, surely). However, using Poweramp with DVC on an old Galaxy S6 that I have laying around is still miles better. Sound quality is my only complaint about this phone, that's why I was hoping for a custom rom for this thing.

Yeah you're absolutely right that DTS is a marketing thing and it sucks, you just keep trying on that poweramp 709 build only and try downloading it from APKPURE or somewhere else because the one that i provided was patched with lucky patcher and i hoped it would work with a non-rooted device to skip the activation process but apparently that is not the case, after i reflashed the phone and got rid of the root access i had to install poweramp unlocker and i have to reinstall the the main app every 2 days because without the root i can't seem to be able to activate it, keep digging, i know what a good DAC sounds like, it's not an HTC native level but it's miles ahead of the stock drivers and even better than viper4android module on magisk.

No worries about that. I've purchased the app years ago. The only thing now is that I can't allow it to update. Thanks for the hint, the sound is clearly better now.

Question Can you improve the sound of the speakers / emulate Huawei's "Stereo+"?

Hi,
I recently got a S21 FE and while I'm pretty happy with it, I feel like the speakers are far below acceptable.
Up until now I owned an, by now 5 years old, Huawei mate 10 plus. It was a middle class phone with normal speakers - nothing fancy. However the sound quality is still much better. It got some "Stereo+" setting that only activates in landscape + certain volume but it improves it a lot.
Since there is no additional hardware build into it, it has to be done by software. Is there a way to get a similar effect on Samsung phones? I tried the build in equalizer but it didn't do much nor did it really improve things.

Whiteout root no

Could you explain why not? I do not need the exact feature, I just want a similar sound which should be possible with equalizers or something similar, or not?

Codecs , replacement and tweaks like this I know. Equaliser settings not enough https://github.com/Briclyaz/NLSound_module_QCom example

In the settings for the tone:
Switch off "Dolby Atmos"
Set the Equalizer to "Jazz"
Like this you will have a much more warm speaker sound.

Additionally you can try Poweramp Equalizer from google play store. It's got a load of features for the equalizer.

I'm using Wavelet https://play.google.com/store/apps/details?id=com.pittvandewitt.wavelet
It's a good alternative to Viper without root
Also jetAudio player has a lot of audio settings
