A new Precision option in Minimize Small Pops, that
replaces Extra Precision + Low frequency drums correction
and gives one more (higher) precision level.
New Precision
settings are:
| |
Low - Fast and poor quality, it's equivalent to disabling
Extra Precision in previous versions.
Normal - Balanced speed and quality, it's exactly like enabling Extra Precision in previous versions.
High - Slow, it's like enabling Low frequency drums correction
in older versions.
Very High - If you have a fast multi-core computer and/or can wait, this new setting is for you.
|
|
|
| Progress bars are back! |
|
 |
|
|
Optimized memory management in multi-core computers. Now these fast computers can process long audio files (even longer than 30 minutes) using less memory than older versions.
|
|
Reverse Channels option in Stereo Modifiers filter. You don't have to switch wires if some of your stereo records have inverted channels.
|
|
Low priority mode. You can optionally enable this new advanced option if you want to just forget that DePopper is processing your files in background, while you use other programs in your computer. If you minimize DePopper, you won't even notice its presence while it processes your songs.
|
 |
Developed in new environment. Versions 1 and 2 of DePopper were
developed in Visual C++ 6.0. New version 3 was developed in Visual Studio 2008.
Version 3 is much safer against compatibility problems with Windows Vista and
Windows 7. It's also ready to make better use of the new features of these
operating systems.
|
|
Unicode support. Now DePopper can accept file names and
other texts with Unicode character sets.
|
|
Multiple CPU support. In computers with many CPUs (dual core,
tri core, quad core and so on), with enough memory, DePopper
will increase the speed of most filters (Small Pops, Filter Frequencies
and so on) by using parallel processing.
|
|
CPU usage control. This advanced option adjusts DePopper
use of the CPU, for computers with low heat dissipation.
|
|
Free main window resize. DePopper screen size in pixels remained the
same during almost ten years, while monitor resolutions increased considerably,
much more than their sizes. This made DePopper screen to look smaller,
because today the same pixels take much less space on screen. Now it's possible
to resize DePopper main screen by dragging the bottom right edge, like
any other resizeable Windows screen. The new screen size is automatically saved
when DePopper quits.
|
|
External encoding. DePopper can use an external program to encode
the processed file to your preferred format. For example, if you want to encode
flac, now you can, even if DePopper
does not have built-in flac. Just download the
command line encoder (flac.exe)
from the original web site and
use it in DePopper, as described in the program documentation.
|
|
New Presets feature. Use predefined settings in accordance to your
needs, or create your own presets based on your specific adjusts. This is
a very fast way of automatically optimizing DePopper settings for
your kind of audio sources, like 78 rpm, scratched LPs, well preserved LPs,
classical music or tapes.
|
|
Temporary Files advanced option removed. Now DePopper always
overwrites the destination file many times, avoiding "access denied" issues
in some computers.
|
|
Flexibility. Advanced Options is now available in the
Options screen, as well as in the system menu.
|
|
Less vulnerable to registry damages. DePopper key code and permanant data
are stored in Windows Registry, in accordance to Microsoft guidelines. Some
other programs were deleting DePopper data and key code, forcing the
program to ask for the key code again. This is not a DePopper problem, this
is always caused by other programs erasing DePopper data, but we did some
changes in order to make DePopper less vulnerable to other program erasing
its registry keys.

|
Fixed a bug with mono wav sources in Minimize Big Clicks with Extra Precision enabled.
That filter was not working properly with such source files in that precision mode. Stereo sources
were not affected by the problem.
|
|
Fixed a bug that prevented Presets from working properly when default Documents folder was a network drive or a mapped root drive.
|
|
Fixed a crash that sometimes happened when clicking the Stop button while processing.
|
|
Fixed a crash that could happen in computers very low in memory, when using Minimize Small Pops filter.
|
|
Fixed disk space validation bug with network and root directories.
|
|
Fixed some possible freezings with disk full.
|
|
Fixed a problem that happened in some XP computers with mono files.
The problem only happened in a very small number of computers, and
only with mono files, so you don't need to upgrade for this reason
unless the problem happens to you.
|
|
New first use defaults for Minimize Big Clicks filter. In order to
keep the speed of previous versions in computers with one or two logical
CPUs (single core and dual core), the first use setting for this filter
is not Extra Precision disabled, as before. In tri core and quad
core computers, the first use setting is Extra Precision enabled,
which is faster in computers with many logical CPUs and also gives better
sound quality in a wider range of records. This change affects new installations
only (first time installations and installing after uninstalling). Programs
that are already working and are overinstalled are not affected. You can
always change the settings the way you want, this is only a first use
default, to give a better experience for those who are trying the program
for the first time.
|
|
Added a new advanced option for copying temporary files instead of renaming
them. This solves a rare problem that happens when the computer does not
allow the temporary file renaming (from _TMP to _NEW).
|
|
DirectShow decoding for all computers with Windows XP, Windows Vista;
and Windows 7.
Computers with older versions of Windows may require installation of
Microsoft DirectX® 9. Other audio formats can also be decoded, if the
adequate filters (codecs) are properly installed. Computers without
DirectShow can still process uncompressed WAV files. Although DePopper
can decode lossy compressed formats, we recommend the use of uncompressed
WAV files ONLY, to get the best possible audio quality.
|
|
Command-line Switches for automatic processing from a bat file
(for advanced users - require experience with DOS).
|
|
Temporary Files use in Advanced Options had its default changed to Overwrite Destination Many Times. Although slower, this method is safer against recent changes in Windows file management, that were causing "Access Denied" errors.
|
|
Detection of abnormally terminated previous session. DePopper is very CPU intensive, which requires a CPU cooler working properly, or the CPU will overheat. If the CPU overheats, problems like lockups and reboots may happen. We cannot avoid this because this is hardware problem, but now DePopper detects an abnormal termination in the previous session and displays a message informing the possibility of the CPU problem.
|
|
HLP files changed to CHM, for Windows Vista® compatibility.
|
|
A new Advanced Option for disabling the use of temporary files. Change its settings if you are getting “Access Denied” or “File or file name locked by Windows” errors when processing your files.
|
|
A new option in Minimize Small Pops filter, which allows to enable extra processing which removes an extra noise that appeared in some bass drums, when played alone.
|
|
A new option in the new Big Clicks engine, allowing the removal of frequencies below 38 Hz for fixing cliff-shaped big clicks when Extra Precision is enabled.
|
|
A new engine for Big Clicks filter, more accurate, which is enabled by checking Extra Precision in its setup.
|
|
The possibility of removing a range of frequencies, in addition to isolated frequencies.
|
|
Anti-clipping and gain adjust in Frequency Normalization.
|
|
Improvements in Preview.
|
|
Accepts drag & drop to files window.
|
|
Improvements in volume normalization by using adaptive compression in order to avoid distortion by clipping.
|
|
A new noise minimization filter with much better results for cassete sources.
|
|
New pulley option to filter out very low frequencies when minimizing small pops.
|
|
Optionally turn off NT class machines after processing (if allowed by software, hardware and user permissions).
|
|
New preview button.
|
|
New help entries for visually impaired users.
|
|
A new option to filter out very high frequencies (noise)
and very low frequencies (rumble and pulley noise), as well
as 50 Hz and 60 Hz noise.
|
|
Creation of log (report) files can optionally be disabled.
|
|
Processed files can be stored to source files directory or,
optionally, to a single, fixed, different directory.
|
|
Now it is possible to automatically delete original files after processing, saving disk space.
|
|
More flexibility in file renaming, by adding the possibility of configuring suffixes for old, new and temporary files.
|
|
A new Advanced Options screen, which lets the user to change the settings for auto help feature, opening splash screen, file deletion and file renaming. The new screen, for advanced users only, is attached to the System Menu (top left small disk icon or Alt-Space).
|
|
A new engine for noise minimization, much easier to setup.
There's no need of a "noise figure setting" anymore. DePopper
now identifies the noise by analyzing the dynamics of the
entire sound file, in a much more automated way.
|
|
Improved engine for big clicks minimization gives you less
false detections and therefore less distortion, if you need
to enable this option.
|
|
The program is now more tolerant to WAV files generated by other softwares,
but still requires 16-bit uncompressed format as input. 8-bit formats are
now accepted, but they are converted to 16-bit (doubling their sizes). Most
AVI files with uncompressed 16-bit audio streams are now supported (video information
is discarded).
|
|
We added an extra precision option for small pops minimization.
This mode is somewhat slow, but gives you very high quality results.
|
|
We added an automatic help mode: the help window appears
to the right of the program for each feature you use. You can
disable this feature, of course.
|
|
Distortion problem fixed. In some specific hardware configurations, when processing an audio file that was recorded with excessively high volume (with severe distortion by clipping), DePopper was increasing the original distortion even more. Now the distortion is no more increased, but anyway we never recommend recording with a so high volume. A distorted source will never generate a good processed file. If a very high volume is desired for some reason, we recommend increasing the average volume after processing the audio file with DePopper, using dynamic compression to avoid clippings (the filter Normalize Volume does this).
|
|
Some compatibility issues with directories marked as system
in Windows XP.
|
|
Distortion in frequency normalization with sound files that
have short high volume segments between long low volume segments.
|
|
A crash with sound files saved by some programs with long names.
|
|
A click near the end of some WAV files.
|
|
Small (in size) and short (in time) volume variations at regular intervals.
