Need some advice

[fruityalfred]

Hi, I'm a beginner. Thank you for this wonderful tool! I need some advice.
What di I need to to in order for the most basics? Reading a track, analyze, and play the loop from given points using in my own Python script?

This is what I have: But it always plays the Track from beginning and not from (loop_start=4084130, loop_end=4577835)

from pymusiclooper.core import MusicLooper
from pymusiclooper.handler import LoopHandler
from pymusiclooper.analysis import LoopPair

min_loop_duration = None
max_loop_duration = None

audio_file_path = "F:\Musik zum Mixen\Test.wav"

loop_handler = LoopHandler(path=audio_file_path, min_duration_multiplier=0.35, min_loop_duration=10, max_loop_duration=20)

loop_pairs = loop_handler.get_all_loop_pairs()
print (loop_pairs)

if loop_pairs:
    first_loop = loop_pairs[0]
    loop_handler.play_looping(loop_start=4084130, loop_end=4577835)

Regards,
Alfredo

Hey there! I'm glad you found this tool useful.

Just to clarify, for programmatic access to PyMusicLooper's features, the only thing you'll need would be the MusicLooper class from pymusiclooper.core (and maybe download_audio from pymusiclooper.utils for YT downloads). Any classes/functions inside pymusiclooper.handler are mainly runners/dispatchers for the CLI, and although they can technically be used, they are generally not suitable outside their intended use in the CLI. With that said, using MusicLooper is actually very simple (I may be biased, but I did make it as easy to use as possible!). Here's the minimum you need for just the basics you mentioned (reading a track, analyze, and play the loop from given points).

from pymusiclooper.core import MusicLooper

# String is prefixed with r to make it a raw string,
# so backslashes in the windows directory are not interpreted as an escape sequence
audio_file_path = r"F:\Musik zum Mixen\Test.wav"

try:
    # MusicLooper loads the audio first from the given path
    music_looper = MusicLooper(audio_file_path)
    # Find loop pairs with the defaults
    loop_pairs = music_looper.find_loop_pairs()
    # Take the first / best ranked loop pair (interactive selection using a preview is encouraged though)
    best_pair = loop_pairs[0]
    loop_start = best_pair.loop_start
    loop_end =  best_pair.loop_end
    # Play looping with the chosen loop start and end
    music_looper.play_looping(loop_start=loop_start, loop_end=loop_end)
except Exception as e:
    # An exception is raised if the audio fails to be loaded/analyzed, or if no loops were found
    print(e)

And that's it. If you don't want it to play from the beginning and start somewhere else, you can specify a start_from point in play_looping, like:

    # Play looping with the chosen loop start and end, starting from the loop directly
    music_looper.play_looping(loop_start=loop_start, loop_end=loop_end, start_from=loop_start)

Using other features instead of play_looping should be straightforward, but if there are any issues feel free to ask. I'll be adding better documentation for programmatic access to PyMusicLooper in the future, but in any case, hope this helps!

Thanks a miilion for your kind and very helpful response Nabil. If you offer to ask some questions, I'll take advantage of that. Is it possible to filter for the Score and is it possible to define the amount of samples (or seconds) between the search for loops? I'm asking because it detects a lot of matches from 0 to1 from 1 to 2 and so on, I'm searching a way to configure it that way, that it starts looking from min1 to min2 , min3 to min4 - something like that. I like to get a better varation of loops from a track. I hope, I was able to explain it correct.
