Improving Quality of Recordings
Because we’re using analog signals, the audio recording quality depends on the quality of the device you’re using. In our experience, new iPhones have super good audio quality and older ones too. New iPads are good as well. In the Android world, it’s more varied. In the laptop world, Macbooks do a good job and again, due the variation in the PC world, it’s harder to nail down the best candidates. We’re not promoting Apple products willy-nilly. They just have good audio.
So what we’re saying is that you have to experiment a bit with your own equipment since there are too many Android and Windows devices in the world to get too specific. If you find that your device is really good, let us know and we’ll edit this answer.
But here’s the thing – let’s say you have a device that we’d rank a B rather than an A, with our picky ears. It probably means that there’s some hiss in the recordings. That’s no show stopper, it’s just not ideal. The point is, if there is some hiss, it probably not that big a deal for practical purposes. Another important thing to note – if you put the recordings into an audio editor like Thinklabs Audacity, or Adobe Audition, or TwistedWave, you can run the sounds through a filter and cut a lot of the noise your recording device inflicted on the signals.
Also, you can connect a USB Audio device, such as the Asus Xonar into your device, thereby adding an external audio device that’s much better than what your laptop has. This is a small gizmo that’ll give you much better audio quality. So there are a number of things you can do if you happen to have a lousy sound card in your device.
