Work also in my W7 system.

"Illegal instruction" sounds like too much CPU optimization?

@forclip:
No SSE2 indeed
Therefor only bassAudio_SSE.dll works on my WinXP pc. The two (SSE2) bassAudio.dll work perfectly on the Win7 laptop.
Thanks a lot!

forclip, I have 2 feature requests, if I may:

- Do you perhaps have the knowhow to add support for tracker-files?

BASS' own add-ons; basswma, basscd, bassflac, basswv and bassopus, don't have an underscore in their original filename. You'd have to add one manualy for BassAudio to work.

- Have BassAudio accept the original filename (without underscore) of BASS' own add-ons.

For such kind of files another method must be used (BASS_MusicLoad instead of BASS_StreamCreateFile, with appropriate flags). I don't think I'm very interested in it, so..

Most probably this was done to filter out all *.dlls in current folder, so only those that are bass-plugins ("bass_" prefixed) will be BASS_PluginLoad'ed.
Theoretically there can be other dlls, AviSynth plugins (if someone decided to put everything in one place), runtimes. It seems quite reasonable to not try to load them all.

I'm glad that it now works for you too

Firstly it tries BASS_StreamCreateFile, if it fails - BASS_MusicLoad with BASS_MUSIC_SINCINTER and BASS_MUSIC_RAMP (and BASS_STREAM_PRESCAN | BASS_STREAM_DECODE | BASS_MUSIC_POSRESETEX, required for bassAudio). Works for me, but I have only one such file, so "untested".

I don't know any Avisynth plugins that begin with "bass", so "bass" as prefix would suffice just as well and can easily be changed in line 132 of bassAudio.cpp.

Wow, thanks a lot! All tracker files I've tested so far play flawlessly.
I do however have some samples that have several "chapters", like Twilight.umx for instance. Foobar2000 (with foo_dumb) shows me the file consists of 4 segments: segment 1 (2:18), segment 2 (3:49), segment 3 (0:50) and segment 4 (4:15) (11:12 in total). BassAudio (and DC-BSM btw) only load segment 1 and I don't know if BASS is capable of loading all segments.
I've uploaded Twilight.mka (Twilight.umx encoded to a 48Kbps Opus stream and muxed to Matroska with chapters), in case you don't have foobar2000, so you can listen to all segments.

Well, bassAudio.dll, bass.dll . Anyway, I like how it currently is, I don't think it is so hard to rename those plugins after downloading. How often it is required? Surely not every day.

Twilight.umx - can be played in a very tricky way. Here is a short explanation. But knowing starting positions "in orders" doesn't make a lot of sense, it's only part of the problem. So I would say that bassAudio will stay limited in playing such files..

I agree.

I was thinking about this problem and I don't found a easy solution.

[Reino]

Understood. Thanks for you effort, forclip.

[tebasuna51]

New stable release BeHappy-0.2.6.34898e including BassAudio new versions.

[StainlessS]

Thanx tebasuna51

[LigH]

tebasuna51 for keeping the project alive and jones1913 for the now merged multi-threading fork.

Ok, after 300+ downloads without complaints my beta release can be considered to be stable.

Some days ago I made a mini svn commit but I though it was not worth to pack a new release.
If someone will try I have just uploaded a built (.exe only) to mediafire.
EDIT: removed invalid link

Anyway I have a few ideas to further improve the usability but this will not happen this year.
I hope I have more free time next year to work on this app.

[tebasuna51]

Thanks to jones1913 and forclip, I only join your jobs.

And thanks to siella, and Tom Keller, for the extensions pack, I don't include the pack (only I correct a bug in previous FraunhoferMp3) in the release because I don't have time to check all new encoders, and each user is free to add the needed ones.

Also to CoRoNe for force us to improve the app.

Thanks to jones1913 and tebasuna51 for keeping alive behappy project. I found bug but i am not sure so i ll test again and i ll report in here. Problem is behappy doesnt decode bit of ac3 audio file correctly. I looked ac3 file with mediainfo and it gave 16 bit but when i try to decode with bassadio, ffaudio or nicac3 behappy show 32 bit float.

[LigH]

Again this confusing topic...

Most lossy audio compression technologies with psycho-acoustic spectrum masking (like MP2, MP3, AC3, AAC...) work in a floating-point mode, they will transform the samples into audio spectrums of brief blocks and store parameters of a Fourier transformation. Decoding them back into samples again will return floating point samples at first. They may be converted to integer samples later, or not, depending on the decoder.

I don't know which resolution of 16 bit MediaInfo reports. That may be the resolution of the input samples which the encoder used. But that doesn't matter. As soon as there is an AC3 bitstream, there are no more 16 bit integer samples. Only a sequence of encoded frequency spectrums in AC3 blocks.

[tebasuna51]

LigH

BeHappy preserve the output of the decoders (32 bits float, max precission in AviSynth) and only downsample when the next encoder don't support this precission.

Or when you, manually, add a Convert Sample To ... function.

[jones1913]

Maybe declaring this as stable was a bit too optimistic.

I found an error in jobs start logic, but it was actually only noticeable when using DSP scripts with initialization delay (eg. normalize filter) or source plugins which are delayed while creating an index (LWLibavAudioSource).
In this case jobs can simply crash or can finish with "done" status but with broken audio output file (with size of only a few kB).

I have just commited a fix.
Now a job is only started if the previous job has properly initialized and reached at least a progress of 1%.
This can lead to a more delayed start of each job now (depending on source/dsp filters and filesize).
But of course correct audio output is much more important than speed.

SVN-builds can be found in my mediafire folder. (Link also in my signature)

[jones1913]

Happy new year to all!

The last days I had some time and so I have worked through the code to see if Im able to extend the extension system,
for more functional and visually rich extension plugins (good advertising slogan he?).

Until now I was not very familiar with the xml-deserialization technique used by BeHappy, but it was actually quite simple to understand.

What I have done so far is:
- added some more elements to multi-option class so we can add a trackbar, comboboxes and checkboxes additional to the existing radiobuttons
- renamed some things (all plugins must be recreated anyway)
- make the current plugin configuration saveable in behappy save state file (as before)

old:


new:




Of course all extensions needs to be recreated once this is finished , but I hope that someone can help me then (TomK.? siella?)

More infos soon..

[LigH]

Now that will certainly be a Happy New Year!
