Spectrogram seekbar

Let the select to see a spectrogram seekbar instead of the waveform seekbar.


A spectrogram looks like this:


A spectrogram shows the use of frequencies for each point of a track (x-axis = time, y-axis = frequency, coloring = loudness).


This way you can recognize low quality audio files, since they have a large black border at the top, because high frequencies have been cut.


i can nothing see in your spectrogram that is what i mean ;)

here test this


so you can compare (See what i mean)

that is not optimized for fast reading yet only for testing.

by the way
I did not say that your work is wrong.
I can not see only what I hear
In my Spectrogram I can.

It is a bit hard to say what the difference is without having compared you version with Neons version. Please open a bug report with comparison data so that I can see in detail what you refer to. I have not found any problems seeing/hearing sweeps/faded/freqs etc.

i have upload a sample for testing Take a while ;)

is not a bug in Neon so is not needed create a bug Report..

only what i say is i can not see what i hear.. (Hmm ... my bad english)


greets

I will download and test this tomorrow. I'm still not sure what you refer to :)

You are rendering your spectrogram "unshrinked", e.g. a full-width spectrogram with scrolling.

This makes every chunk larger in your view, because I shrink the width and interpolated the values.


Example:

1) You have a picture A which is 2408px width

2) In Neon we can say that this picture is displayed at 1024px, shrinked and interpolated

3) In your app you display 1024px at a time, with scrolling instead of shrinking and interpolating


That's the reason why data looks diferent.

>>That's the reason why data looks diferent.

yes :)

and that is i can see what i hear.

So, it is not a bug, it just relates to how data is displayed. I can easily both see and hear for example a fading (loud > silent) part in Neon.

A scrolling spectogram in Neon is not relevant at the moment.

I have no scrolling spectrogram :)


only flip to the next Page after the marker (Scrolling line end in Bitmap is reached)

>>So, it is not a bug

have always said that there is no error
only a design technical
Picasso is not Michelangelo
When Michelangelo you immediately recognize what it says with his pictures
When Picasso probably less

No, sorry, that's not the perfered behaviour.

The end user needs to see the entire position slider at once to easily be able to skip within the whole file without any paging.

If you use Neon with a huge display you will get more or less the same look as in your small application.

Here's the interpolation steps smaller than with a 1920*1080 resolution.


See the attached picture:

i understand you.. :)

Neon is your baby and you can do with it what you want.
