For a long time my favourite media player has been Clementine. This is a powerful, well-featured and easy to use player that also has the benefit of being available across several different platforms, so I can use essentially the same player on both my Linux box at home and my Windows PC at work.
Amongst other features Clementine, like all good media players, has a set of equalisation controls. One of my minor niggles with the program is that access to this is buried in the Tools menu and there doesn’t seem to be any way of configuring a button on the interface or a keyboard shortcut to bring the equaliser panel up.
(Of course, since Clementine is an open-source project I could in theory hack the source code but that would involve quite a steep learning curve and way too much work, so I think I’ll just stick with using the menu. I may see if there’s a channel for getting feedback to the dev team, in case it’s a feature they’d like to consider for future releases).
Slight fiddliness of access notwithstanding, the equaliser is pretty straightforward to use. In the version I have on my home computer (Clementine v1.0.1 for Linux) it is a 10 band graphic equaliser with sliders marked for frequencies between 60Hz and 16kHz (both of those probably pushing the limits of my PC speakers, not to mention my own hearing) as well as a pre-amp fader. There is also a facility for saving, loading and deleting presets, with a fair selection of pre-installed presets, mostly named for different musical genres (such as Classical, Rock or Ska) though there are a few others named for other things (Large Hall, Full Bass etc.). While the sliders don’t have any marked scale on them, there is a nice feature whereby you feel a definite notch as you slide through the centre point (i.e. between cutting and boosting the given frequency). It seems to be done by momentarily pausing the fader button when you drag it through that point but it gives an impressively tactile sensation for an on-screen slider.
Most of the time I tend to leave the equaliser alone but it is sometimes quite handy to be able to tweak it. I had a clear demonstration of this yesterday.
Earlier in the week I’d been listening to an AC/DC CD (or at least its digital representation in my media library) and had actually got round to resetting the eq to the Rock preset, which has a classic smiley face slider configuration (i.e. bottom and top end pushed up and middle pushed down a bit), though skewed slightly to the left. This gives a nice bit of sizzle to the sound which generally works well for rock music (hence the preset is quite aptly named).
Yesterday, though, I came to play a vintage opera recording that I’d only just picked up and never previously heard (Renata Tebaldi singing Catalani’s La Wally, c. 1950, in case you’re interested). The sound was disappointingly thin and crackly and I thought this was a problem with the recording (it was, after all, a cheap CD of a 64 year old recording). Then I remembered about the EQ and, on checking, discovered that it was still set to Rock. I changed it to Classical (flat up to 3kHz and then slightly attenuated for higher frequencies) and it was immediately transformed to a much richer, fuller sound without the annoying hiss.
Apart from being able to access the EQ panel more easily, I’d like to have a facility whereby you could save your EQ preferences for each track or album in your library, rather than having to reset the equaliser manually each time. This would be especially useful when listening, as I often do, to a mixed playlist of music from different genres.
It is obviously good to be able to adjust the equalisation of your music files in order to be able to get the best possible sound for the combination of the recording, the musical genre, your playback equipment and your own personal tastes. Perhaps less obviously, it’s also good sometimes to be able to to vary the EQ in order to bring out different aspects of the music. Not only could this be a way to help you listen to a familiar piece with fresh ears but it can be very handy when you are trying to transcribe a piece of music as, with a judicious choice of EQ settings, you can emphasise the particular section of the sonic spectrum that you are trying to make out and reduce the amount of clutter from everything else that might be going on at the same time. I’ve been trying to transcribe several pieces of music in the past few days and have just been discovering how useful the EQ controls (as well as other technological marvels such as the ability to slow a piece down without lowering the pitch) can be to aid in this task.
