I have the following patch that can play just fine one audio file based on button press

I will have an encoder rotary that will print numbers between 1 to 9 and I would like to play tracks accordingly
what is the best method of playing multiple files without the need to multiple everything?

Thanks

@KMETE I suppose you have to preload the tracks using [[sf-play2~]
It is a lot easier to use [readsf~] and play tracks by message.
If they are named with sequential numbers the button press numbers could replace $1 in the [open....( message.

With [sf-play2~] I think you will have to use multiple players as you did here......

Thanks, I will give a try for the readsf~

I was wondering if there is any difference between multiple sf-play2~ or readsf~ in term of memory usage?

sf-play2~ accepts a symbol in the right-hand inlet, to change the buffer being played. (That is, this -- "With [sf-play2~] I think you will have to use multiple players as you did here" -- is incorrect. I'd be a terrible programmer if I made the abstraction so inflexible.)

[stereofile] loads the contents into RAM. (sf-play2~ is only the player, not the loader, but it depends on audio data loaded into RAM by stereofile.)

readsf~ streams from disk so its RAM usage should be much smaller.

One of the reasons why I worked on stereofile and sf-play2~ is that I think if you tell it to play an audio file at rate = 1, then it should sound like the file's normal speed at any Pd sample rate. Pd's built-in [tabplay~] does not do this -- if the system sample rate differs from the file's rate, it will play faster or slower than normal. That is, system settings affect the patch's behavior . I think [readsf~] also has this problem but I haven't checked, could be wrong about that.

@ddw_music thanks! that is great feature changing the buffer being played from the right-hand inlet of the sf-play2~

I would like to build a few system like those that each system will play a different album of a musician. so one musician will have an album with 7 track with different names and another musician will have an album with 5 track of different names.

the one thing in common that all track will be numbered but I'm assuming that the names of the track will be with spaces - for example:
01 sunny days are over
02 hello
etc etc

what is the best way to load multiple track into buffer with track named as above? Do I must change the names to be without spaces? 01_sunny_days_are_over 02_hello

should I make a list of names inside a coll object? should I make a doc files in the patch folder and load the names from it? what is your suggestions?

Many thanks

@KMETE There is a Vanilla solution....... for all spaces in the file path and the file name.....
concat.zip
It will fill the spaces with an empty symbol and create a single symbol, without having to know about the format as you would have to with [makefilename].
David.

@ddw_music - so in any way I will need to have multiple stereo files objects corresponds to the numbers of tracks in the folder?

I try to understand how can I play different audio files that are placed in a folder with different names without the need to copy each track path or name individually rather be able to play it only based on is numbering 01 name 02 different_name 03 another_name

etc

edit:
what is that I am asking is how to avoid multiple pathnames like this? is there easier way to read into buffer different files sitting in the same folder that are numbered 01 02 03 etc without the need to copy their unique name?

@KMETE

only 1 stereo file is needed. I just need to change the path to each track I want to play..

So I guess this is the direction I should look for:

how can I add index number to each name outputted from the [file glob] object?

@KMETE If you give all the files a number instead of the name it is easy and you don't need [file glob]

AAaaargh...... should be [declare -path] ... not [declare patch]

Output directly into the inlet of [sf-play2~] that takes the file name.
Then start the player....

If you don't then you need to assign a number to each file.
You cannot add it to the name because [sf-play2~] will only play the actual file name.
You have 3 options.

1. change the names to numbers before you start.... as above.
2. automate replacing the file names with numbers using a command line script after [file glob]....
3. associate, in Pd, a number with the file name........ cart5.zip

For it to run in vanilla you will need to get the missing externals, or replace them with the appropriate [file] objects.
[tof/folderpath] [ext13/strippath] and [folder_list]

Dynamic patching......... there will now be another way using [list store].
It creates a [tracklist_button] for each file in a folder and displays it in the sub-patch [pd tracklist].
Each [tracklist_button has 2 arguments.
The first is the file name.
The second argument..... 1 to n...... is the associated number assigned, and sending that number into [s playit] will send the original file name into [readsf~] which can of course be [sf-play2~] instead.
David.

thanks but I would prefer to find a way to play the tracks without the need to change their names.

I got complicated now. I think that what I should do is to store all tracks in a folder as paths into a Coll object and adding them indexes (otherwise I can't add them to Coll) and then use the Coll to read to each track by their index.

the issue I'm facing is how to change a path folder with spaces into one I will be able to read in the file object ? then how to add to each line of path a index and store it into Coll?

how can I prepend an index to each item from the second picture and delete that 0 at each item end?

Ok I think I got it! using zl group and list funnel

the next thing I try to solve is that I needed to delete any spaces in the folders name so I will be able to read the files. Is there any way I could do it without he need o change the names so no spaces are

@KMETE That was a pita...... backslashes now allowed and messing with everything + errors in help files......
This will get you the file names from a directory even when the path to the directory contains spaces..... globby.pd

Best not to have spaces in the file name...... difficult to deal with because of backslashes..... can probably be done with concat and other things......
If you want the whole path and filename then remove [file splitname] onwards....... but the backslash problem returns if there are spaces in the path name.

is it possible to use the lobby patch without the use of the open panel ? rather just pass a path in a message box?

@KMETE Still struggling with spaces.
This will (where there are no spaces) assign numbers to your audio files in a known folder (globby modified)....... all vanilla... cart6.zip
Start the files by sending the number via [s playit] or clicking the appropriate bang in the [tracklist] window.
I got part way solving the space problem, but it will have to be done later unless you beat me to it.
Change the folder name to yours........ top left of "guts" window...... open the small colourful gui of cart6.pd.....
There will be stuff left that is redundant I am sure.

@whale-av I have downloaded zexy library that includes the [l] and [l2s] objects and added it to my pd search path but I'm getting error " l2s ... couldn't create

edit:
When I looked inside zexy folder I can see that the object [l2s] is not exist

@KMETE sorry that I didn't spot that one........ in zexy it is called [list2symbol] and its short name was [l2s] in Pd extended....... there were a lot of useful short names in extended, but now they trip us up.

AND I just spotted an error..... as it was originally built with a random function.
You should remove the cord from the right hand outlet of [readsf~].
It seems that now (from what Pd version I don't know) that [readsf~] can play multiple files at once.... but sends a bang from the right inlet claiming to have finished every time it gets a new filename as before.

So here is all of it updated including a vanilla [l2s]........ cart7.zip
Hopefully all good....
David,

@whale-av Thanks but I think that the object [l] is also not appearing in the zexy folder

@KMETE sorry again......
Change [l $1] in [tracklist_button-vanilla] to [symbol $1]
Let's hope there are no more.
Done here........ cart7.zip

[l] was short for [lister] in zexy

P.S.... better....[l2s] and [lister] removed and all tidied..... cart8.zip

Spaces when I get a moment to experiment and research.
David.
