You can do what you want, just sleep for slightly longer then the length of the beep.
In this case Sleep(1501)

Generally It isn't 'dangerous' to not release resources. However if you create them in a loop (say 10000 steps), there might be a memory overflow.

Why don't you use one Global Beeper for all your needs. You won't have to worry about Sleep() and B.Release, there will only be one resource, which will be released when the App is killed by the OS.

A global Beeper can be (re)initalize(d) as many times as you need with different parameters.

Use a global variable and initialize it once.

I was thinking a set of different beepers with different frequencies and durations. However their number would still be relatively small and each could easily be initialized once.
[Curiosity makes me ask why not initialize multiple times, like we do with Stringbuilder? ...still learning]

Beeper is one of the rare objects that have a release method. You do need to call Release before you initialize it again.

any chance of getting a good code example. On all threads for the beeper, there are a lot of suggestions, but wouldn't it be nice to have a working example.. I understand that coding is a kind of goal for you but for us it is a tool to mkae the tools we need to have working........
support and code examples are the most welcome for that..

Some people even do not mind to pay a little for that, even while the software is free nowadays......I made this suggestion more times...

i don't know exactly what is your comment (my english is not very good,... best to say: is very bud).
In the first post are the code.
that is:

B4X:

Dim B As Beeper
            b.Initialize(150, 650) '300 milliseconds, 500 hz
            b.Beep
            Sleep (150)
            B.Release

or create a PUBLIC VAR ( Dim B As Beeper) in a process_globals and only do this:

B4X:

    b.Initialize(250, 300) '300 milliseconds, 500 hz
            b.Beep

It is never a good idea to post in old threads.

Best to reuse the Beeper object.

For every small remark, starting a new thread... Isn't that an overflow on forum threads? For searching of the topic it does not become easier.. And a topic/problem is often half solved and then people start referring to the existing topics which are always only half of the answer... Most forums like to keep it compact and more depth...

Not this one. And I don't agree about searching. No one will ever find a question that was posted in the 17th post of a thread. Anyway, this is the policy in this forum.
