Serious flaw in program

I discovered a serious issue with SF Audio Cleaning lab. When opening audio files in the program, it will create a HM0 file. In these small files the peaklevel and audio waveform data is saved for the audio file that was opened.

So far so good, HOWEVER the program will always save the HM0 file in the original location of the audio file that was opened. And that creates issues !!!!!!!!!!!!!!!!!!!!

For instance I have loads of FLAC files on a NAS. For security reasons the folders are all "read-only". However SF ACL tries to save the HM0 files all the time in the originating folder, which is read-only, so the result is that I can't use the program to edit audio files.

PLEASE implement something so the user can determine in which file location the HM0 should be stored. Since there always is a Project file, there is no need to always save them in the original audio file location. After all the Project file can point to the location of the HM0 files

Please remember these are user to user forums, not a contact for any Magix employee so I doubt that your pleas will be read by anyone in a position to make any change of this nature!

I have to say, speaking personally, I don't find the behaviour you are commenting on as a "flaw"! Every audio editing program I have stores any associated data files directly with the original audio file. This is to ensure that the program can easily "find" them again and so not have to recreate them if/when the audio file is re-opened.

At least one program I use does allow the user to specifically NOT save the associated data file; I don't think SFACL has that option.

Two questions:

  1. Which version of SFACL are you running, 1 or 2?
  2. I assume you are "editing" your FLAC files. Is that correct? If so, since they are in folders which are "read-only", how can any audio editing app save them back to their original location? I assume you must be putting them through some kind of intermediate process in order to save them on the NAS. If so, what?

. . . . a serious issue . . . . . For security reasons the folders are all "read-only" . . . .

There are a lot of programs that create supplementary and temporary files in the same folder as the file being read so I would not call this a serious issue, more of an permissions issue

A common practice is to make the folder permissions Read/Write only for Authenticated user, Users or a User security group, with inheritance disabled and the files within them Read only.

I am not familiar with Sound Forge Audio Cleaning Lab but SF Pro creates a similar <.sfk> waveform file for fast opening. SF Pro has an option to "Hide new temporary files" so they are not visible. They can also be deleted without issue to the main audio file. I do not know if the ACL has the 'hide' option .. I do not know if the .hmo file is a project file or a waveform file. Waveform files can be deleted (or hidden) if they are an annoyance.

In any case, I do not consider it a "flaw" either.
