how do I use the equalizer apo:
My laptop’s sound quality straight from the headphone jack (no additional external amp/dac) improves dramatically using the apo equalizer. before I got my first dac/amp, it allowed me to achieve a level of sound quality that I had never experienced before. for some reason on my computer the apo equalizer has no effect on my dac/amp (outperforming dx7s), which is fine because I love how my dx7s sounds, but it’s worth pointing out because everything I say here just It is directly applied to the laptop headset. audio jack (at least in my case). i have also downloaded the equalizer apo on all my friends and coworkers laptops (none of which have separate amps/dacs) so they can have better sound quality. it’s a good first step in getting people looking for better sound quality (hopefully leading them to buy a dac/amp and good headphones).
Reading: Equalizer apo headphone presets
I currently have two equalizer presets for each of my headphones and speakers: one for music and movies, the other for mostly talking youtube channels (such as talk shows, product reviews, how-to videos). for any specific piece of audio, I can dial in the settings to make the audio sound perfect for that specific file, but doing so is time consuming and I’m happy with my current two preset method. each of my individual presets compensates for the specifics of individual gear, but a general description would be that my music/movie presets have increased highs and lows (treble and bass), while my youtube talk presets They have reduced bass, slightly reduced mids and boosted treble. movies and music sound the way I expect them to sound with boosted bass and treble (vibrant, punchy, uplifting) rather than no equalization (flat, neutral, dull). with heavy talk programming on youtube i found that almost everyone has a dull midrange hum surrounding the voices (male and female). Whatever the reason, the voices always have a low, muffled quality around them that I’ve always found annoying. with my youtube talk presets, I lower the midrange and raise the treble, which removes the extra muffled quality and makes voices sound crisp and clear by comparison (much more like they’re in person rather than speaking through from a poor quality speaker).
my basic method for creating an equalizer preset:
I start by playing a certain piece of audio (song, video, movie). while it’s playing, I start on the left side at the first slider of the frequency bar. I move the slider bar up and down to see what effect it has at that particular frequency. once I know what the effect is on the sound, I start moving the slider in a narrower range until it sounds as good as I can at that particular frequency. then I move to the next frequency to the right and repeat the process. if moving the slider up and down doesn’t change the sound, I leave that slider at 0 (no change). keep doing this from left to right (or the other way around if you prefer) until you’ve manually set each slider to whatever feels like the perfect spot. depending on what you’re listening to, certain sliders (representing specific frequencies) will have more or less effect than others. once you’ve set the entire range of frequency sliders, go back and adjust the settings as needed until you have the best possible sound profile you can create for that specific piece of audio. for short audio, like songs, I’ll have to play the same track repeatedly a couple of times before dialing in the settings.
once you’ve dialed in the equalizer settings for a specific piece of audio, save the setting as a preset labeled for audio and equipment type, then play a different piece of audio of a similar type (music, movie, etc.). conversation). Starting at the first slider again, repeat the process, but this time remember what setting you started at so you can go back if you find you don’t need any further changes. once everything sounds perfect, move on to the next piece of audio and repeat the process. in no time (within a couple of pieces of audio) you’ll find that your audio sounds as good as you think it can and you won’t want to mess with it anymore, at which point you’re done. this process is how i go about creating the different presets i use. the wider the range of audio types you hear when making adjustments, the more accurate your settings will be. With that in mind, I separate the movies/music from the conversation-focused videos because I want different things from those two sets of audio that I consume. my goal is to hear a wide range of audio, but within the category/genre you have chosen to create the preset.
Doing this is very easy and very productive. I was nervous at first that I was going to mess up the sound, but I quickly discovered that hearing what sounded good or bad is instinctive, easy, and rewarding. turning the equalizer on and off makes it easier to hear the difference you’re making and validate your efforts. sorry if this approach is not technical enough for some people. I’m pretty new to this quest and still learning. learning this helped me a lot to get better audio than before, so hopefully it can help someone else do the same.
