BassAudio - fresh alpha is out! (2006-03-07)

[dimzon]

BassAudio is wrapper around BASS library
http://www.un4seen.com/bass.html

The BASS library is free for non-money making use - if you are not charging for the software (and it has no other commercial purpose, eg. advertising), then you can use BASS in it for free.

Currently my plugin must support

MP3/MP2/MP1/OGG/WAV/AIFF/WMA/FLAC/WavPack/Speex/Musepack /AAC/M4A/APE/MO3 / IT / XM / S3M / MTM / MOD / UMX

Usage sample:

bassAudioSource("C:\ab\Dido\001 Here With Me.m4a")

or

bassAudioSource("C:\ab\Dido\001 Here With Me.aac")

or

bassAudioSource("C:\ab\Dido\001 Here With Me.mp3")

Warning! This is REALLY alpha version - i need testing from You!

интересно!

Maybe you have a look at Libavcodec, as it supports many other formats too (http://ffmpeg.sourceforge.net/ffmpeg-doc.html#SEC20). Compiling it as shared dll (without demuxers/muxers/encoders, so just the decoders) and handling the avcodec.dll access the same way you did in your approach on the bass.dll could be a nice step.

Beside this ... IMHO MugFunky some time ago asked for a LibavCodecSource() for video handling purposes, but If you compile Libavcodec incl. everything, it can be used to decompress everything supported by libavcodec for avisynth purposes.

http://www.inb.uni-luebeck.de/~boehm...ibavcodec.html

I know theres a ffdshow support for avisynth, but maybe such a plugin could be more handy. Who knows.

Nope Cologne, my russian bases on maybe 5 words, these are the only ones I know:

- Interesno / interesting (just encountered)
- Harascho (?) / very well
- Priviet / Hi
- paka / bye bye ?

A long long time ago I knew some parts of the russian alphabet as the russian language seemed to be (is) very very interesting

[dimzon]

talking about BASS
fist attempt was to write generic WinAmp plugin wrapper to allow usage of WinAmp input plugin
Then I perform some google-ing to find another players with plugin support. I have found XMPlay and BASS...

[Inc]

There's also "Fmod". AFAIK it supports beside decoding many sound processing algorhythms.

I have compared it - BASS allows much more formats to be decoded - AC3/WMA/AAC/OGG etc

[foxyshadis]

Ogg and aac support means I'll be testing it tonight. Does it downmix at all?

[dimzon]

Audio-CD Ripping using this plugin
Download BASSCD 2.2 from official BASS homepage
Extract basscd.dll
Rename it to bass_cd.dll
Place bass_cd.dll near bassAudio.dll
Write such script:

bassAudioSource("D:\Track01.cda")

No. There are possible to DownMix using AviSynth itself - there are no reson to implement built-in downmixer

[dimzon]

quick hotfix/patch uploaded!

[acrespo]

Can I use this plugin to load MPA source files?

[dimzon]

new version is out - now MO3 / IT / XM / S3M / MTM / MOD / UMX file formats are supported

[Fizick]

dimzon,
it is really "interesno"

But can I ask you some off-topic: it is possible to create some Avisynth plugins for more advanced audio processing, for example for old vinil click removal, etc? My expirience is for video plugins only.

theoretically why not everything what we need is algorytm/math... unfortunally I'm not DSP expert

Now I'm seriously thinking about generic WinAmp DSP plugin wrapper or/and generic VST plugin wrapper...

[chros]

Haven't you see this on http://www.un4seen.com/ ?

BASS_WADSP 2.2 (.0.5) : An extension enabling the use of Winamp DSP plugins with BASS. C/C++, Delphi and Visual Basic APIs are included.

AIF LOADER!!! YOU WIN MY INTERNET!!

sorry bout that... i'm excited. the spruce cards here produce aif files, and it's a real pain to convert them to wavs for processing in avisynth. also sucks because soft encode doesn't accept big endian raw files (and if it did there'd no doubt be a click at the start from the file header).

this plugin means i can make a batch process to convert aif to wav, then send that wav to soft encode without the operator having to lift a finger. thanks heaps

If anyone provide me API for direct invocation of AC3 encoder dll from soft encode i will write my own commandline frontend with pipeline support (direct AIFF->AC3 transcoding without WAV files)

[Inc]

I think if you use a dll function names parser and Google using one of these function names, maybe youll get on a site where the correct accessing is explained - depending on IF softencode somewhere/sometime did release an API Listing for developers of their dll.

i will write my own commandline frontend

Btw. Softencode does support Commandlining directly so you can include its acces in Behappy?(maybe at least this helps):
http://forum.doom9.org/showthread.ph...ght=softencode

So you even could support .avs-->.ac3 using Softencodes DVD compilant and correct volume output in Behappy IF stdin input support in Softencode is given.

So the supported arguments of Softencode are:

Sonic Foundry Sonic Foundry Soft Encode - Dolby Digital 5.1

-A -o <outputfile> -L <left> -R <right> -C <center> -l <sleft> -r <sright> -e <LFE>

-A Auto Encode
-o Output file encoded
-L Left channel file
-C Center channel file
-R Right channel file
-l Left surround channel file
-r Right surround channel file
-e LFE channel file
-O<channel> to -5<channel> Set channel of given file
e.g. -2L (use second channel of left file)
-c Audio coding mode (default 7 = 3/2 mode)
0 = 1+1 (L, R)
1 = 1/0 (C)
2 = 2/0 (L, R)
3 = 3/0 (L, C, R)
4 = 2/1 (L, R, l)
5 = 3/1 (L, C, R, l)
6 = 2/2 (L, R, l, r)
7 = 3/2 (L, C, R, l, r)
-cr RF overmodulation protection on/off (default 1 = on)
0 = off
1 = on
-f Frame size code (default 14 = 384 kbps)
0 = 32 kbps 7 = 112 kbps 14 = 384 kbps
1 = 40 kbps 8 = 128 kbps 15 = 448 kbps
2 = 48 kbps 9 = 160 kbps 16 = 512 kbps
3 = 56 kbps 10 = 192 kbps 17 = 576 kbps
4 = 64 kbps 11 = 224 kbps 18 = 640 kbps
5 = 80 kbps 12 = 256 kbps
6 = 96 kbps 13 = 320 kbps
-g LFE filter flag (default enabled)
-j DC filter flag (default disabled)
-k Compression characteristic (0..5) (default 0 = off)
0 = no compression
1 = film standard compression
2 = film light compression
3 = music standard compression
4 = music light compression
5 = speech compression
-F Low frequency effects channel on/off (default 1 = on)
-m Perform digital deemphasis (default disabled)
-s Sample rate code (default 0 = 48 kHz)
0 = 48 kHz
1 = 44.1 kHz

Nope. I need STDIN support to avoid temporaly WAV files...
Hmm... Seems it's time to lean SoftIce...
