The old post about this topic made someone confused, so I write this new one according to infinitymusic’s request. Just ignore this if you have your way to detect real quality of mp3 already. Anyway, I think this is necessary if you are new to mp3’s quality.
The bigger the mp3 sounds, the higher the quality is.
But some software can help improving the sound, make it sounds bigger. Make a 128kbps sounds like a 320kbps one. So I rarely use this way, especially for the small difference between 192k and 320k.
Software you will need to use:
– foobar (Recommend v0.9.5.2 or lower); there are many soft help us in detecting the quality. But in this post, I’ll show you how to use foobar.
You can download this software through filehippo’s website.
* I know foobar’s default skin is a little bit “ugly” to you guys, but it supports many skins that you can download from the Internet. In case if you are wondering which skin I’m currently using now, follow this link
– Open your file with foobar
– File > View > Visualisations > Spectrogram
Right click in the ‘Spectrogram” window,
+ Style > Scrolling
+ Scale > Linear
– File > View > Visualisations > Spectrum
Place these new windows like this pic (Right click > View Image to see a larger picture)
This is how the REAL 320k will look like
The spectrum nearly reaches the top in the ‘Spectrogram’ window. The red line zone = space of the first song in playlist (my English is bad so I hope you understand what I’m saying)
Here is the 192kbps (the zone in the pic = space of the second song in playlist)
Apply the same rule for 128kbps.
I don’t pay more attention to the lower bit rate, but the spectrum will be lower when the quality is worse.
*NOTE: Depend on the encoding method, some real 320k will have the low spectrum. I’ll let you know in the post when the album/ single meets this problem.
Any question about this, you can ask here. Feel free to discuss the topic.
