I probably made a mistake by writing a message that was too long to talk about the social context rather than the software, and this took everyone's time away. Not even I have tried to reproduce the defect reported by Kraeved, I preferred to postpone it to the weekend because I work with macOS, Linux or in any case with compatible Posix command lines and I need more time to not sacrifice my family between work and this tiring passion .

We try to understand each other, the method is right, Kraeved gave us the indications to reproduce, it takes longer to get feedback and I probably stretched them unnecessarily and gave a bad example.

E:\GLAZBA-WORK>chcp
Active code page: 852

exhale works fine if it is in folder with other cmd tools I use, and folder is added to PATH variable. When executing exhale from another folder that isn't in path, it completely ignores folder I am in and searches for input file in folder where exe file is. And it should first search for input file in folder I am currently.

Code: [Select]

So, as I tested, and from my lifelong experience with command line tools, exhale doesn't work "by the book". It should look in current, working directory for files first, then in it's own directory, and only then throw an error. It shouldn't skip lookup. And I don't think it has problem with unicode, I think it has problem with where it searches files first.

@Kraeved I'm not here to moderate this post, but you should really change the way you are posting.
I will assume that you had a misunderstanding (either caused by non-native language or by using impersonal communication means like a board) and got Helmrich reply wrong. … Instead you blamed him for not being able to reproduce your problem plus some racial bla bla..

The way I write changes depending on the behavior of the other party. When the other party produces spaghetti code, then does not try to debug as it works on his end, then gives a formal reply on the app’s issue tracker with no intent to help such as “if exhale.exe -V displays Unicode flag, than Unicode is there, dixi”, then the communication goes downhill, obviously. So there is no language misunderstanding here. Make no mistake: doing something for free in your spare time and sharing it is great, but does not grant access to the hall of fame by itself. When you share something, expect to process various feedback, not exclusively positive, because there is a certain level of expectations set by the achievements of ancestors. The feedback includes bashing, because there are more and more quitters who fuel expectations but fail to deliver — let’s hope Christopher Helmrich does not belong to that tribe and Exhale’s bugs are caused by COVID-19 ambience, not by a lack of dedication. That said, I am still polite and follow the rules of beloved Hydrogenaudio, but no longer try to cajole that particular developer. Instead, I promoted examples of decent development and provided more details about bugs. As for “racial bla bla”, it’s called reasoning by analogy, but oh well.

Now, back to Exhale. Its path bug happens in Powershell (5.0) as well.

it is about a unicode.

That is correct, at least for Windows. It needs to explicitly have a wmain function, or it needs to use something like FLAC does on Windows, which is hooking other functions to perform argument decoding in UTF-8, and decoding filenames in UTF-8, and printing output to the terminal in UTF-8 where necessary.

Indeed, the DRM standard linked to by celona (thanks!) recommends PS only in the range 18 - 26 kbit/s (see sec. 5.4.3), and I second that recommendation. The FDK-AAC encoding of "Boat to Havana" above averages at 61 kbit/s, so should definitely not be using PS. And the bitrate-comparable exhale preset is "c" here, not "g", by the way.

OK, thanks to the others I understood the issue (path vs. Path/PATH) now. So I made a new commit which (1) mentions exhale's Wiki in the ReadMe (explaining the presets and listing the associated bit-rate ranges) and (2) changed exhale.exe to consider the current working directory instead of the called application directory. That issue was never a bug but intentional behavior, as the ReadMe or exhale itself when called without any arguments explains. That switch from application to current working directory isn't activated yet under Linux/Mac/ARM yet, though, since I can't test it. Any help here from other developers is appreciated (change line 64 in exhaleApp.cpp to "#define EA_USE_WORK_DIR 1 ..." and let me know if it works).

Regarding Unicode: exhale has all that, a wmain etc., under a macro EXHALE_APP_WCHAR in exhaleApp.cpp, line 35. Maybe that's not activated with some compilers?

Enabled the workaround mentioned above, apparently something went wrong with the existing define for celona? I just set the whole macro to 1.

Universal x86_64 / arm64 build, as usual. exhaled unstripped but signed, exhale stripped and signed. Hardened runtime. Notarized. (And in case anyone asks, you can't staple CLI executables.)

Thanks, I only use the command line compiler and I don't know how to do it. In the meantime I have verified that it works with Linux, I leave you the usual version for SoC ARM v7l: exhale@760f862f-Linux-armv7l.bz2.

Here ya go:

https://gist.github.com/kode54/b4f31ccf1ec8fc2c008eb80522d35e64

Basically, you need all the compile and link command lines to have -arch arguments for every arch you're building or linking. I patched the Makefiles to accept a config switch to turn that on:

Code: [Select]

make UNIVERSAL2=1

Apply it while cd'd into the exhale root dir on current as of this post commit, like so:

Code: [Select]

patch -Np1 -I path/to/exhale_universal2_workdir.patch

And as I said before, for signing:

Code: [Select]

codesign -s <identity> --option=runtime bin/exhale

That much gets you either ad-hoc or not-notarized Developer ID. This document outlines how to manually zip up and submit the resulting code signed and hardened runtime binaries to Apple for notarization. I basically sent them the exact ZIP I uploaded above.

Dear john33, take a peek at the attached screenshot of Rarewares. I highlighted the possible click points in yellow. Do you realize that an ordinary user has to examine the menu and make a few bad choices (starting with Downloads, which leads to the same News page) before Exhale would be found? Why do you torture users like that instead of linking news items to proper site sections at least? O Hypertext, where art thou?

The automatic option # set as the alias of 3 up to 48 kHz is the best choice and certainly the least sophisticated. To convince myself I have listened 5s by Paolo Balestri, the male voice that puts the encoder in trouble reading Dorian Gray in Italian, sampled at each frequency used by Exhale. I am sure that will also be needed in the future because after recalibrating the encoder on this voice, the higher bitrates with the higher sample rates now show problems that I had missed.

Mono wave files
7350Hz - 8000Hz - 11025Hz - 12000Hz - 16000Hz - 19200Hz - 22050Hz - 24000Hz - 32000Hz - 38400Hz - 44100Hz - 48000Hz - 57600Hz - 64000Hz - 88200Hz - 96000Hz .

Stereo wave files
7350Hz - 8000Hz - 11025Hz - 12000Hz - 16000Hz - 19200Hz - 22050Hz - 24000Hz - 32000Hz - 38400Hz - 44100Hz - 48000Hz - 57600Hz - 64000Hz - 88200Hz - 96000Hz .

I saved a set of files with fewer sampling rates, only in mono, processed or rather over-processed, to try to better understand the influence of extreme levels (-16LUFS) in the result.

Processed mono wave files
12000Hz - 16000Hz - 24000Hz - 32000Hz - 44100Hz - 48000Hz - 88200Hz - 96000Hz .

I have used these files with other encoders too and of course the differences are very small, but it's better to postpone these evaluations.

Unicode bug is still there.

Hmm, just discovered something strange. The Windows 7 command prompt does not display Unicode properly because the default cmd font isn't Unicode capable, at least on my German Windows installation. Right-click on a cmd window's title bar, select "Properties" and select font "Consolas". Then I can see and encode existing Unicode-named files and can also give the output .m4a a Unicode name.

Can you rename an existing .wav file to the Russian word (music) in your screenshot and try encoding that file? Maybe it's just exhale's "not found" error message that's buggy.

Igor actually already linked to the Wiki in the very first post of this thread

But I don't blame you, really, the thread has gotten much too long. Maybe I should open a separate thread for bug reports? But then again, we have the GitLab issue tracker for that, which I actually prefer since contributors can link to merge requests there with concrete source code fixes.

Maybe I'll just ask Igor or a moderator to augment the first post of this thread to display a big "PLEASE READ THE FIRST 10 POSTS OF THIS THREAD FIRST BEFORE POSTING A QUESTION OR BUG REPORT!" sign?

Maybe it's just exhale's "not found" error message that's buggy.

Exhale processes Unicode filenames on Windows 7 just fine, Unicode bug is related to the error message only.
Use non-existing path and filename to reproduce the bug: exhale g c:\Небо\птицы-vögel-pájaros-birds.wav out.m4a
Then it outputs ERROR while trying to open input file c:\????\?????-v�gel-p�jaros-birds.wav! Does it already exist?
Its garbled look is barely related to the fonts as I’ve seen this earlier when something is broken (of course, I tried Consolas etc).

I am planning a personal listening test of the latest exhale and the Opus encoder.
Exhale will be tested with and without the SBR.
If nothing is wrong, I'm going to start testing from 2021/04/03.

Below is the bitrate table of the tested samples in bps.

Thanks, I just noticed the same suggestion on a different web page, but it doesn't work, at least not with my VS2012 compiler. See also my reply to https://gitlab.com/ecodis/exhale/-/issues/17. Also, I had to finish this release since somebody is waiting for me, so

the 27e9e9e revision is now the tagged final 1.1.4 release of exhale.

Changes since exhale 1.1.3 from last month:

exhaleApp: removed LUFS/dBFS command arguments again, code now automatic
exhaleApp: consider the working instead of application path if no path is specified
exhaleLib: reduce enc. delay to closest integer multiple of frame length (issue #15)
exhaleLib: very minor tuning of transient coding especially on male speech signals

Looking forward to this, thank you. It would be of great interest to me (and maybe others?) if you could add one high bitrate test at 192 kbs for both codecs for a vocals-with-music source to check how the "9" encoding level of Exhale performs against Opus.

By C/C++ standard, mixing char/wchar_t output to a same stdio file / iostream is not guaranteed to work.
https://stackoverflow.com/questions/8947949/mixing-cout-and-wcout-in-same-program

IIRC, in case of MSVC mixing them is allowed only when _O_U8TEXT/_O_U16TEXT is NOT set.
In other words, if you want to use _O_U8TEXT/_O_U16TEXT in MSVC, you have to stick to wchar_t oriented printing functions everywhere.
