Video convert/ Audio Boost

i have found a lot of programs to convert the video to phone size but one problem remains. is there a way to boost audio strength? i had a program a while back for my mt3g but i cant find it anymore. forgot what it was called.
everytime i play any type of video on my phone and pass it through to my car system its so low that i have to crank it to max. even then, it wont get any louder past 28 and the loudest setting is 35. i know its not my system because at 20-25 it makes peoples ears bleed.
thanks

found a program called formatfactory. settings look pretty cool and free.
it has the audio boost by db.. will try this and post info

I like DVD Catalyst, works great everytime and can modify all the settings including boosting audio volume

[Q] Bluetooth quality issues?

So, posting here was a last resort, but I've exhausted all my other options. I'll try to make this as concise as possible:
I just did a bluetooth/aux input retrofit for my car so I can stop using CDs for music. Aux sounds crystal clear, bluetooth with my 2nd generation iPod touch sounds crystal clear, bluetooth with my Optimus G Pro has static, crackling at certain frequencies. Doesn't sound compressed necessarily, just crackly.
What I've done:
1) Hard reset.
2) Tried both the original 4.1.2 and the new "value pack" update.
3) Actually sent my phone back to AT&T and got a refurbished one in the mail.
4) Sent my bluetooth retrofit unit back and got a new one in the mail.
5) Rooted the phone, installed freegee and twrp, and flashed the hkfriends kernel.
None of this fixed my issues. When playing the same exact song on my iPod and Android phone, the iPod wins every time.
P.S. My friend's Verizon phone (I think it's a Motorola Razr) has the same sound quality issues. Not sure of Android version, though.
Music is the absolute most important thing for me, and if I can't get this resolved I will have to switch back to Windows Phone/iPhone, despite how much I love Android. I have no knowledge or time to develop a new Rom for the G Pro and there's no telling when we'll get one that could fix my issues.
Is anyone else having these problems, or does anyone have any suggestions?
Thanks!

For some reason my phone decided to play music using "Phone Audio". I disabled phone audio for the device in bluetooth setting, then it connected as an AV signal, and quality improved drastically.

Thanks for the suggestion. Just tried it, unfortunately did not seem to make any noticeable difference for me. To clarify, the sound quality is fine for the most part, it's just at certain frequencies I hear crackling.
By the way, earlier I also edited the audio.conf file under /system/etc/bluetooth and changed the values of "SBCSources=1" and "MPEG12Sources=0" to 0 and 1 respectively, which I read should force better quality out of bluetooth. Additionally I changed the value "Master=false" to true, which I also read could improve quality. It might be my mind playing tricks on me but it does seem to sound better, however I still hear the crackling at times, so I'm definitely not where I want to be.
Highly disappointing. Any other suggestions?

Which music player are you using on your phone? And have you tried any of the equalizer apps from the market?
Sent from my LG-E980 using xda premium

I've tried both the Music app that LG includes, and Google's Play Music app, which I prefer. No difference. Have not tried any equalizers, but not quite sure what that would do aside from eliminating the frequencies that have issues through bluetooth but work fine through an aux input? I don't consider butchering the music as an acceptable solution, unfortunately.

try this, it might help

Does this help with volume output?

Just out of curiosity - how did you find out editing the audio.conf file? I'm looking for a way to boost the output volume for my bluetooth, did a quick search and saw your post and it made me curious...
Will this change boost the output volume at all or is there a separate line or file to be edited?
Thanks for your help.

Problems with Equalizer

Hi,
most of the time, I'm using my phone for listening to music, and since I own Galaxy S4 Mini (GT-I9195), I'm thinking about throwing my 320€ worth smartphone in trash. Mostly I'm listening to rock music where basses are very important. When I was using stock firmware, everytime I increased the bass level, the music volume diminished. It came so far, that when I was traveling from work to home by bus, I could hear what people around me were talking to, even though my volume level was on 100%. Then I somehow increased the volume of my phone (I found a thread how to do that here on xda), but then the next problem became annoying. Almost every time I skipped the song, the equalizer settings went back to default. So every time i had to press menu button --> settings --> equalizer, and then basses went back to normal. Sometimes equalizer doesn't work at all, until I reboot my phone.
So I tried with Cyanogenmod today, and I'm even more disappointed with music quality. Every time I try to turn on bass boost, the music starts to crackle, even though bass level is only on slight. I'm using 120€ worth Sony headphones, which work great on any other device, so the problem definitely isn't in headphones.
Does anyone deal with the same problem? I just don't know what to do anymore ...
Thanks in advance & sorry for bad English.

Hello there.
First off, if you are going to throw S4 mini into trash, you can instead send it to me and I'll pay for the delivery, as I simply love the phone.
Secondly, I think the problem is you and not the phone. I have S4 mini and I love listening to music. As anyone who loves music (proffesionaly or unproffesionaly) knows, basses ARE NOT THE ONLY (and most) important thing, even in rock music. And as far as basses goes S4 mini does a very good job, as it does in other spectrums of music playback. The volume decreases a bit if you set it to bass, because the equalizer decreases the treble value, thus you get the perception of decreased laudnes. Although I would recommend you get your hearing checked, as the laudness of S4 mini seems to be laud enough for others.
If you really like to listen to high quality music and are a true audiophile, than you wouln't be listening to the music on S4 mini on the first place, but would go for a high quality professional grade mp3 (or FLAC) player with an external amplifier.
Therefore I conclude that you are just a bass freak who wants to complain, but please feel free to prove me wrong.

My opinion and advice may not matter since I don't own a s4 mini (would love to have it)
But did you tried sound alive from Samsung?
Just increase the bass and some clarity then reverb and room size (if you like) then the bass is on a good level, wanting more bass than that would only get in the way of the guitars part!!
Or try viper4android if you're on a desperate situation...
Can I ask something here?? Is the smart volume feature any good??

@Shiningb
Firstly, thanks for your answer. I realized that everything works perfectly with stock Samsung Music app (which doesn't use build-in equalizer, but uses it's own one). The quality of sound is really great.
Only problem is that I prefer Google Play Music which is much clearer, easyer to navigate and overall has nicer interface. But there I deal with equalizer problem; the sound is great at the moment, the equalizer is set the way I want, basses are great, but then suddenly (without particual reason) equalizer just goes flat and the volume increases for about 30% rapidly which is a great way to go deaf. Then I have to restart equalizer app, and it starts working normally again for about next 10 minutes. Until I won't find the solution, I have to use stock music app, ok, i can get along with this
I googled about the issue and I found that it is quite common with S4 users. I heard about ViPER4Android today, and I'm going to try it right now, thaniks for your advice !
And sorry, I don't know if smart volume feature works good, I use mp3gain app on my PC which equalizes volumes of all tracks on the same level and works perfectly.

This happens with equalizer because the system kills it from the ram
So a great solution is to use viper...
But you need root and put the apk of viper into system/app set permissions to rw-r-r
Like this it won't be killed, because it will make part of the system app
By the way what kind of music do you hear??
I'm a sound freak with viper, I tunr things like crazy until I reach the perfect sound (for a time!)
I really wanted to know how the smart volume works since the I9070 won't have a official 4.2.2 update :'(

Thanks for fast answer.
I installed ViPER4Android, but everything I try to change, doesn't have any effect on sound. I don't know what is wrong ...
Could you help me with Viper? I know how to put a file in system/app and set permissions.
My phone is rooted I'm using CWM and stock android from Samsung.
My favorite artists are 30 Seconds to Mars, Billy Idol, Bring me the Horizon, Foo Fighters, HIM, Kings of Leon, Oasis, RHCP, etc.
Sry, probably really won't. I owned I9000 before I9195 and it was the best phone i ever had, even better with Cyanogenmod

Which ROM should I try for better sound?

I bought my Tab S 10.5 primarily for multimedia consumption on the go. I love the screen and nearly everything about this tablet, including the default software suite. However, from day one I discovered that there is an issue with sound volume. It's too low. I don't mean that I need the sound to blast my ears like I want to lose my hearing. The issue is with many videos and services that were recorded intentionally or unintentionally at a relatively low volume. And so when I play those few youtube or netflix videos, I really need to strain my ears in a noisy environment to hear anything.
Anyways, for me, the sound is the number one problem. Considering the 19:10 screen, this tablet was obviously meant for media consumption. In the light of that, it's truly perplexing that the stock OS has such lousy volume level control. Please let me know the best course of action. Should I try just some tweaking under after rooting, a custom kernel, or an entire ROM replacement distribution?
Thanks.

Wrong thread

Well, I have made some progress on this problem, and fortunately without replacing the stock ROM. I rooted the device with the Autoroot ROM for T800 posted on this board. After that, it turns out that the gain settings are in a plain text file in /system/etc/default_gain.conf. I changed the two lines that said:
{ "HPOUT1 Digital Volume", 121 },
to
{ "HPOUT1 Digital Volume", 161 },
both apparently under "Headphone" and "Headset out" sections near the top of this huge file. I used the ES File Manager's "root explorer" mode to do this. After that, I had no issues with the sound output level. In fact, on my first attempt, I used something like 191, but it made a lot of default sounds way too loud and it also made it possible to crank the volume level even in "quiet" youtube and netflix videos towards quite uncomfortable levels.
I am glad I could get away without replacing the entire ROM, because besides this issue and the time synchronization (also fixed with rooting and 3rd party app), I am mostly happy with the way the stock ROM works.

Wrong thread

hello this is unfortunately digital levels only and it does not adjusts gains of the hardware. Though it helps it produces distortion / bad quality in higher levels. I'm curios if the sound driver is possible to hack.

General Audio driver problems

So wanted to comment on this
First, this is the best phone I’ve ever owned, although its lacking in a couple of things i was used to (coming from a oneplus 9 that had a lot of settings compared to this one, still this is a waaaay better phone) the speed, screen size and battery life makes it all worth it
Though! I use a lot of external dacs through the usb c connector (main reason to have a big battery)
I’m finding some issues in the audio department:
Tidal mqa files are not being played if the dac doesnt have mqa decoding (normally they would play without issues in iPadOS and one ui/ oxygen os
Some dacs (specially ifi hifi link) will not play files until a mqa file is played, though any system sound will interrupt the communication with the dac, it can be fixed played any master quality track and then going back to flac/ hifi quality in tidal, YouTube doesn’t work at all with this dac.
Facebook and YouTube wont play audio sometimes,my theory is that the player goes for the oem 3.5 out instead of the dac. That could be fixed if we got an audio output selector in the notifications player, though the option is not available as the player plays as a simplified notification, so no audio selection is possible
Of course the 3.5 jack in this is quite nice but … usb c dacs are a bit better at handling hi res files and streaming and of course demanding headphones.
Sent already this to nubia. Hopefully there will be a work around, UAPP is a viable solution of course but the easiness to surf through playlists is better in the tidal app.
So anyway, anyone surfing for an answer: its in the developers hands
Just wanted to leave this in case anyone looking in the internet is looking for answers on this
No audio switch app works on android 13 (lesser audio switch, etc)
Although there’s work around for using the external dacs, it comes as a surprise the first times. Though the phone is a beast and i truly love the battery life and extended display, a couple of tweaks and this would be the best phone out there

Kinda figure it out. The DTS ultra app was the culprit, even if it showed the toggle off, it was turning on (and screwing the sound for me) , just disabled the "auto start" or link button on the app preferences. all audio is being processed by the external dac. At least YouTube and fb are working flawlessly so far
Update: Some dacs are still having issues with the mqa decoder, but the general audio is coming out of the usb c port at least.

Hi there. I had the same problem. But I was able to access my DTS Ultra app. It doesn't appear in my app drawer but I found the audio effects app for DTS Ultra using Activitylauncher from play store.
I could be wrong but I also noticed there is no way to EQ the speakers on the phone. The DTS Ultra app only shows up for headphones and gives the "Disconnect External Devices" error on speakers. I find the speakers to be good quality but slightly lacking in tuning, is there any way to perhaps tune them through 3rd party means? Thanks for the help.
