Notes found

Find notes in clean recording - use other programs to clean them first...

The dection of notes is easily confused by background noise or low or high frequency sound.

So to improve the accuracy of the results, first use a sound editor to do a band pass or high pass to remove all frequencies outside the range of interest. Also do a noise reduction.

You could for example use Goldwave.

The count waves method is easily confused by low background noise such as traffic hum, and also by high fequency noise adding extra wave crossings. It can also be confused by any background noise as it can find regular patterns in noise not corresponding to any heard pitch.

The frequency spectrum method is less easily confused but background noise can add extra partials or lead it to detecting a pitch in the noise as the fundamental of the note to detect.

Both methods are programmed for solo recordings, withthe emphasis on high resolution pitch detection of the notes.

Any polyphony is just treated as noise and confuses the method.

Sometimes you can remove other instruments from a polyphonic recording to some degree using bandpass, most likely to be successful with instruments with few higher partials such as bird song and whistle, flute, recorder etc. If successful there, one might then in some cases be able to transcribe each part individually in Tune Smithy and then combine the result.


Recording to temporary memory - time limited by the memory available...

This records directly to your computer's temporary volatile memory (such as RAM or whatever). You can then save the result using the Save Rec. As button in the Temp Rec. menu.

The maximum time for the recording is limited by the amount of memory. On a computer of the last few years (as of 2007) this is quite long, perhaps a quarter of an hour or more. On an older computer it can only make very short audio clips.

You can configure it from the Temp Rec Times window, and choose there how much computer memory to set aside for the recording.

If you want to make longer recordings, limited only by the file space available on your computer, use the Record to File window

Help = F1

Click for help for this window. Or F1. Other opts: Shift , Alt, Ctrl + click...

F1 or click shows the help for the current window in your web browser.

Some windows may have no help yet in which case the help icon is shown crossed out with a red line.

Shift + F1 or Shift + Click brings up the tool tips extra help window (this window) to show any extra help for a tool tip.

You can tell if a tool tip has extra help if it ends ... like this one.

Ctrl + F1 or Ctrl + click takes you to the list of keyboard shortcuts for Tune Smithy.

Alt + F1 or Alt + click (alternatively Caps lock physically held down + F1 or Click) takes you to the on-line page at the web site about the current main window task - which gives a short introduction to it for newbies to the program. If there is no on-line page specific to a task, takes you to the main tune smithy page on the web site.

Since the help for Tune Smithy is currently a bit out of date and needs to be redone completely for the new 3.0 release, then you may find the on-line page for some of the newer tasks particularly useful.

Organise Windows = F2

Reset, or Save settings for this window. RIGHT CLICK for all windows menu...

Shows the Organise windows window - which you can use to reset all the parameters for the current window.

You can also use it to save the settings for just this window, or open previously saved parameters for just this window.

Also has a drop list of all the windows and their shortcuts, and related options - some to do with the menu listing, and some to do with window resizing and minimising.
