1. Installation:
If you have downloaded Wavosaur from https://www.wavosaur.com you have a zip
archive file called Wavosaur.x.x.x.x.zip. And thanks!!!

So now, just unzip the archive, there are only 2 exe files in the archive:
- the Wavosaur executable (Wavosaur.exe)
- the VSTScan application (WavosaurVSTScan.exe)

Note that Wavosaur:

- doesn't need installer
- it doesn't write into the registry or in Windows directories
- and in general, it doesn't need any external dll. If dll files are necessary,
there are inside the zip file.

Note about 32 and 64 bits versions: two versions of exe files are usable depending
of what you want:
- for 64 bits operating systems, it’s possible to use both versions
- for 32 bits operating systems, only 32bits version is usable

To use 32 bits VST, you must use Wavosaur 32 bits, and 64 bits for 64 bits.

 Wavosaur quick start guide

1.1. Configuration files:

It's recommended to create "Wavosaur" folder and place the application

(Wavosaur.exe file) inside the directory.

Wavosaur creates configuration files to store settings and user preferences:

- wavosaur.ini
- wavosaurbrowser.ini
- wavosaurmidicommand.ini
- wavosaurrecentfiles.ini
- wavosaur.cfg
- wavosaur.vst

Wavosaur works without these files (but if you delete them, you'll lose your
configuration settings). If you need to reset your configuration, just delete these files.
There are also editable (text file format).

During a session Wavosaur also create temporary files that are deleted when the
user exits the application.

1.2. Editor skin preferences:

You can also download optional .skin files used for storing the "skin preferences" of
the editor. See the Editor Configuration chapter for more information.
These files can be placed anywhere, it's a good idea to store them in the Wavosaur
folder.

2. Configuration:

2.1. Audio configuration:

Go in menu Options → Audio configuration

Audio out:
This tab displays all the MME drivers available on your system.
Select the driver you want for audio playing.

Buffer size:
This dropdown menu lets you change the buffer size for audio playing,
If you experience glitches or crackle when playing, try to increase the buffer size
value. The more the buffer size, the more the latency, decrease the buffer size if you
want a better latency.

Sample rate:
This dropdown menu lets you choose the sample rate for audio out. Don't forget to
adjust the buffer size if you change this parameter and want the same latency.

ASIO Driver:
This checkbox switches between MME & ASIO drivers. (for the audio output only
atm). If your soundcard doesn't support ASIO, you can install ASIO4ALL.
Choose your ASIO driver in the audio out tab (see next figure).

https://www.wavosaur.com
Copyright © 2006-2023
 Wavosaur quick start guide

Realtime resampling:
When checked, Wavosaur perform real-time resampling: audio output is resampled
to the samplerate frequency chosen for output.
If you uncheck this box, file with samplerate that differs from the output samplerate
will play faster/slower.

Audio in:
This tab lets you choose the audio driver for audio input. Choose here your line input
or mic input for recording.

Buffer size:
Change the buffer size if you experience glitches/missing buffer when recording.

Sample rate:
Choose the sample rate for your recording.

These settings are saved in the .cfg file. If you delete the .cfg file, Wavosaur resets to
the default configuration.

2.2. Audio routing:

Go in menu Options → Audio routing

Depending on your soundcard/drivers you can have more than two outputs.
This configuration window lets you choose the routing for audio output.

The left tab displays your soundcard outputs.

The right tab displays the Wavosaur channels (= the .wav channels)

Select in the left tab the soundcard audio output, and make it match to the wav
channel you want.

- You can send the main stereo channels (0 & 1) to all your outputs.
- You can send all the 16 wav channels to different outputs (if you have enough
audio out!) for multichannel wav.
- You can invert left & right outputs.
- Etc.

number and byte order. You can also select an offset to skip the first n bytes of the
file.

3.2.2. To export file:

Go in menu Files → Export → Export as MP3

You need the lame_enc.dll to be present in the Wavosaur folder.
You can choose you bitrate for MP3 encoding:

Note: mp3 is compressed file format with losses for each time you save it. That the
reason why it’s better to export the file only at the end of your work.

marker is inserted to show the beginning of the record.

Check your audio configuration to select the audio input and samplerate.
Bit depth is 16 bits, you can change to 24 bits recording if your soundcard supports
this bit-depth by editing the wavosaur.cfg (AudioInBitDepth).

Dirac at cursor insert a 0dB sample at cursor

Step at cursor insert a step at cursor (replace the current file)
Frequency impulse train insert frequency impulse train (replace all datas)
Frequency sweep generate a sweep signal from 0Hz to sampling frequency
divided by two.

10. Troubleshooting:

No sounds can be heard:

→ check your selected audio drivers (menu→Options→Audio configuration).
→ depending on your soundcard & drivers be sure there's no other program that use
the drivers.
→ check also the audio routing (menu→Options→Audio routing).

There are some glitches/crackles when playing/recording:

→ try to increase the buffer size in the audio configuration

The latency is too high:

→ go for ASIO, if your soundcard doesn't support it, try ASIO4ALL

I lost my skin!
→ if you change/move/rename the .skin file, Wavosaur can't open the skin
informations and reset to the default editor look.

MIDI control doesn't work:

→ check the MIDI configuration if the right MIDI in port is set,
→ set the MIDI CC (editable in the wavosaur.cfg) to match with your hardware.
