Recording at 24 bits enables you to leave a little more 'headroom', while still maintaining more than enough dynamic range to dither down to 16-bit when you come to mix, but even 16-bit audio has a maximum dynamic range of 96dB, and I think you'll find that the ratio of signal to ambient background noise in project studios is typically worse than 65dB. Finding the correct solution involves taking a hard, honest look at what you're doing and the way you're doing it, before rushing out to buy that esoteric valve microphone or 24-bit/96kHz converter. If you're trying to record vocals in a small room, it's easy to end up with a boxy sound. In a way, this makes a lot of sense.

The choice of mic will make a difference to the timbre of the recording, but a good singer will sound fine whether recorded using a dynamic stage mic or a high-end capacitor model. However, it's really not that difficult to set up an adequate monitoring system, as most furnished domestic rooms with carpets make passable monitoring environments provided that you work reasonably close to the speakers and don't choose monitors with too great a bass extension. It is much easier to get a good recording of a Zoom meeting than a phone call, but sometimes the use of video can cause just as many issues. However, you can also get a good sound by moving the mic right up to the speaker grille, and you'll find that you get a useful tonal variation by moving the mic between the middle of the speaker and its edge. Record the result either flat or with a little compression and all you'll need to do at the mixing stage is add a hint of reverb to flesh out the sound. The quality is low (even with great microphones) and usually, there are little to no features at all. If you're trying to record vocals in a small room, it's easy to end up with a boxy sound. It's also important that the singer feels comfortable, which means setting up a good headphone monitor mix with enough reverb on the vocals to help accurate pitching.

Part two of this rule is not to point the mic at the loudest component of the sound, such as the end of a wind instrument or the sound-hole of a guitar. On occasions, breaking this rule can produce good results, and many sax recordings are done with the mic pointing at the business end of the instrument, but in most cases you'll get a more accurate sound by backing off and aiming the mic away from the 'loud spot'.

You may also find that a digital system comprising multiple components sounds significantly better when clocked from an external word clock generator, as daisy-chaining devices can lead to excessive jitter, resulting in increased noise and distortion. When using a sequencer that includes plug-in processing, it's usually only necessary to ensure that the channel and master meters are reading sensible values, but if you have outboard effects or processors, you'll also need to check that their input and output levels are set to make the best use of the available dynamic range.
