Lead-in time for tracks

[BJG145]

Quick question...what's a sensible lead-in time for tracks being submitted for digital release (CD Baby, Bandcamp, Spotify etc)...?

[RichardT]

I usually have a lead in time of about 0.25 seconds.

...thanks, when I looked this up the other day I was finding 2 seconds which seemed excessive. Checking it again it sounds like this was recommended for CD, but unless you're releasing on CD I guess it can be shorter...?

2 seconds was kind of a default time between CD tracks. A 1/4 second or so is fine.

Yes, for streaming, shorter is better. Listeners expect the track to start just about straight away.

A 2 second or longer lead-in is compulsory for the first track on a CD although the CD player skips that lead-in and goes straight to the index 1 on the first track.

I'd normally leave at least 0.1 seconds before the audio starts to give any player time to unmute before the start of the wanted audio.

OK! Thanks...

I've experienced quite a number of digital audio playback systems that fail to play the first 100-300mS of audio, from CD and DVD players decades ago to modern apps. Sometimes it's faulty programming and is fixed in an update; sometimes it's a hardware issue that will never change.

Whether you'd want to include a gap to take that into account would be up to you. I think no gap (very common) is foolish.

Unless it's for a CD, I normally leave 1 second of silence as a lead-in. I find if I'm using something like Soundcloud, that allows me to drag back to the start of the track and play almost instantaneously, whilst if I leave anything much shorter and drag back, the track always starts just after the beginning. Which sort of ties-in with Sonic's experience.

Soundcloud definitely needs a lead-in, it’s quite a bad offender.

I too standardise on a 1-second lead-in, by cropping the track start visually to the very start of its waveform, and then physically adding 1 second of silence (as others have mentioned, shorter lead-ins can occasionally result in the first note getting cut off in some applications).

I never use anything longer than 1 second, and it really annoys me when others do so, as after a few seconds have passed and you still can't hear anything, you're bound to suspect faulty playback.

I then adjust the spacing between tracks using the end of each track as required, adding extra silence if necessary.

Interesting. I'll have to take that into consideration.

Soundcloud also tends to need a bit of a lead-out as well.

Personally I find half-a-second tends to do the job but obviously this is not a consistent experience.
