If u want the best sound out of these earphone.....
There are certain mod
First use spinfits.....dont use other buds because i have tested 20 people and they were getting best sound
Equalisation part:
This comes from the "s/w equalizer for multiple audio formats" thread, but I decided to start writing in a post because I think this can be interesting enough to have its own thread and title:
The advantage of using a convolution plugin for equalization is that it allows to equalize your playback using any equalization you can have access to, including the ones available at wave editors, mastering programs, DirectX/VST plugins, hardware equalizers (both analog or digital), etc.
So, in practice, all this can be achieved on realtime playback using a convolution DSP plugin, such as RealReverb convolution plugin for Winamp. However, this doesn't allow realtime adjustments from the plugin or from Winamp, and requires to generate an adequate impulse respose externally. Still, you can do your real-time adjustments outside Winamp (for example, using any of the eq./filtering possibilites from CoolEdit), and generate an impulse respose that corresponds to the desired equalization, and feed the convolution plugin with it.
How to generate an impulse response? Well, I played with this some time ago, and there can be some details that could be optimized. Still, the basic procedure would be:
- Find the eq. you need/want.
- Pass a "perfect" impulse through this equalization.
- Feed the convolution plugin with the resulting impulse response.
In detail:
1 - First, you have to generate an "perfect" impulse signal. For this, using an audio editor (CEP in this example), generate 0.5 or 1 second of silence, in mono, 32 bit, 44.1 KHz (or the rate your music is recorded at). At the middle of this silence, edit 1 sample and set it to full scale. This is a delta of Dirac impulse signal, it contains all frequencies from 0 to fs/2. you can save it, so that you don't have to repeat this step again.
2 - Now, find the equalization you are going to use. You can use anything you want, from external analog equalizers, or FFT, FIR, IIR, short, long, filters, anything that can accept a signal, equalize it, and ouput the result. For example, in CEP, you could use the built-in graphic equalizer, or any of the other filters it has. Play your pink or test signal from CEP, and make your eq. adjustments so that you get the tightest and clear response.
3 - Now, you have to generate the impulse response equivalent to this eq. For this, simply apply your equalization to the delta impulse generated at (1), and there you have it. In order to optimize the convolution, edit the impulse removing as much zero samples as possible before and after the impulse. You will have to use the zoom to check this properly. Convert this impulse response to 16 bit, using preferably flat (no noiseshaping) dither with triangular pdf, 1-bit amplitude. Haven't tested what effect would have noiseshaping dither. Save this as a wav file, and you have your desired impulse ready to be used.
4 - Now, just downloadand install the RealReverb Winamp convolution plugin (Google for it), and configure it in Winamp so that it uses as impulse response the one you have generated.
The Winamp output should have the exact equalization you "designed" at CEP.
Now, some things to know:
- Convolution is slow to compute. The shorter the impulse response, the faster it will run.
- RealReverb just accepts 16-bit data, IIRC, although 24-bit or floating point impulse responses would result into less noise at the end.
- RealReverB doesn't dither the result, but in practice this is not much of an issue.
- Using this same procedure you can add reverberation to your music, using a suitable impulse response, including impulse responses recorded at real auditoriums or theatres.
- An convolution DSP plugin for FB2K would be nice
This way we correct the eq with least load and lag on music
