Speaker playback - Android Software/Hacking General [Developers Only]

I'm a Metalhead n need playback of my Metal tracks to be good quality on the phone if not great ! Everything else plays fine than a Rock/Metal track. Its no doubt that the audio quality on the headphones is great. I also understand that those low quality speakers on the Optimus suck.
So now what's the solution to eliminate the crackling + hiss sound?
Can I apply some software application? Can I change the speaker hardware? Can I alter the music files in a way that they dont produce crackling sound but still sound loud enough on speakers?
P.S : Many of the music files I download are originally encoded at a low volume i.e. some of the music files are low volume, while others are higher volume (based on how they were encoded by the uploaders). I always amplify the volume using the freeware "Wavepad" due to the low volume of files. I experimented by first applying a reverb to the files n then amplifying them to see if they no more produce a crackling sound.
Please help me if someone knows what I'm talkin abt.

I almost solved the issue of the crackling/hiss sound on speaker playback by playing around with the software "Wavepad".
In this software, I applied the following to the mp3 files in the given sequence:
1. Automatic Gain Control
2. Equalizer - Band Stop
3. Stereo Pan
4. Amplify - 200% to 300% (max)

Qtek 8310 sound

Can you tell me how many speakers 8310 has? When I play mp3 song from it (192Kbps), it plays sound from the speaker which is used for conversation. And the sound is not very loud (earpeace volume is set to maximum).
Is there only one speaker present? Should I avoid playing music, in order to keep the quality of the speaker on the level it is now, since I don't want to loose conversation sound quality?
Tornado has just one internal speaker
This is not true, it has two of them, one for the earpiece (very tiny) and one for the speakerphone, also used for the ringer. Just search the net for photos of disassembled Tornados or other HTC smartphones.
If you play music and do not have the headset connected, then the bigger speaker is used - and you can't kill it by playing music. The smaller one is only used for phone conversations. The volume level label "earpiece volume" is misleading - it always levels the complete system output audio level (it seems to be stored separately per profile or per situation, e.g. "in call" is remembered separately). It is usually set to full level. Applications (like media player) should not adjust this master volume, but their own playback volume only.

XT720 loudspeaker

is anyone hearing cracking and distortion from loudspeaker when playing music/or receiving incoming calla - at volumes above 50-60%?
the same thing is happening in earpiece (when volume is above 60%)
I have singapoure software, so is this common problem, or some hardware malfunction? :/
try to use 256 kbps audio mp3 or mp3 with higher quality...
i turn the volume to 100% still no distortion from my xt720...
No distortion to me at all.
I think it's individual

Low volume with anything other than Google Music

Volume was very low through my earphones (I've tried multiple), so I looked around the forum for similar threads. There's a LOT of threads with low volume issues. I found Voodoo Control, installed it, and configured it to output maximum levels. Google Music is at an acceptable level now where I won't put it to maximum volume, but Moboplayer sounds like I have it at ~50% when I actually have everything maxed out. It's pretty much useless to watch a movie where there is any other noise even with my in-ear phones that isolate sound.
I'm running the original Prime 1.5, not the revised kernel (no SoD issues here). So I'm getting a bit desperate here because of all the other little issues I've had to deal with this tablet... What can I do to resolve this?
I can't be the only one with this issue. Google Music's volume is more than sufficiently loud after installing Voodoo Control and maxing out everything. I originally thought my problem was limited to Moboplayer, but it's anything else besides Google Music. I've viewed my videos through Mobo, Rock, and the built-in MyNet app. I have normalized the audio stream to 100% for my videos, but even when set to "max" volume, it is nowhere near loud enough if there's any other noise in the environment.
I really want to like this tablet (and I do to some extent), but there's all these little issues with the software and some hardware that are really making me -__-
I can't say I have this issue but I can say that the sound quality sucks and even at the highest volume it is too low.
I installed Power AMP which has an equalizer with a Loud Speaker Out Pre setting which is louder than anything I have seen yet. It seems when you set your tab to this any other music player will pick it up and it is definitely louder.
Give it a try.

[Q] xperia z3 speaker problem

Anyone here having problem on the speaker? When i test ringtone in sound picker and try classic phone or cassiopeia there something weird sound in my speaker
Yes I do too
What kind of sound? Like a distortion you mean? At maximum volume?
I think he means that vibration or something loose like sound that comes on certain frequencies. I only get it in calls at full volume sometimes but not with music playing.
Ah yes for calls it might happen. But if you are listening to music with a high bitrate (high quality), you should not hear any other noises. Because low bitrates (low quality) music can make weird noises at high volume.

Question Sound dies down when the bass drops.

When playing songs at full volume with outdoor mode on at full volumes the vocals die down when the bass hits, it sounds like a cheap Bluetooth speaker. Anyone else facing the same issue?
Please try it and let me know if the vocals get dim when the base hits.
Try the Song Glass House by MGK or any of the drake songs.
Thank you
Your sure it's not a sound system issue?
If the device performs well with quality headphones it's likely not the cause.
You should be coming out in the 24bit digital realm if possible otherwise it will degrade the sound quality if the source is high fidelity.
Hi.
So I noticed this issue early on and I tried the song you mentioned and have replicated the problem.
Except, I don't think it's a bug. In outdoor mode, the volume is boosted but at that volume the bass would be distorting in these speakers and therefore it lowers the overall sound.
You can replicate this even without outdoor mode on but with bass slider at max in audiowizard. You will get the same problem.
So, it works this way because that's how it's designed. Unfortunately.

Alright thank you, but that's the thing I mean the speakers are good but you cannot use them to their full potential, the front camera is absolutely terrible for video calls, Snapchat is just a blurred face, I mean what's the point of this phone when it cannot get the basics right it overheats but 40C is acceptable. But thank you for confirming, I thought there is some hardware issue with my phone.
I think that's just the audio processing trying to compensate for the bass and prevent speaker over-excursion with soft clipping or dynamic range compression. The speakers are inherently limited in size and as far as I know, the phone doesn't use the entire back or front to improve bass response (like LG's Boombox feature).
You can try to EQ the bass down or disable the DTS processing.

Use Poweramp for complete equalizer control.
It's limiter works flawlessly.
If the phone 24 bit digital output and you use it there should be no issues on the phone side.
