What's new in version 2.8.0.0 (latest update)
What's new in version 1.2.0.10 to 2.8 (previous update)
What's new in version 1.0.2.204 (this page)

Sample Champion Release 1.0.2.204 and above.
These are the latest updates in Sample Champion (still not included in the manual):


File exporting and importing options


 

(1) When an Impulse Response is exported as WAV, the data values of the Impulse in the WAV file are normalized (WAV file values are integer between +/-32767).

(2) When measuring a STEREO IR or Scope, here can be selected the exported channel (TIM files support only 1 channel).

(3) A WAV file, when loaded, can be recognized by Sample Champion as Scope or Impulse Response Data. When loaded as IR, the values can be optionally normalized (4).

(5) Here are some options for exporting Fequency Data.

(6) Here are some options for exporting Impulse Response Data.

(7) Here are some options for exporting Scope Data.

(8) Simple Form exporting option enables a simplest format of the exported Impulse Response and Scope Data.

In Sample Champion version 1.0.2.202 and above, ASCII(TXT) Impulse Response files measured by using other software can be imported. Only single channel Data are accepted. The format of the imported files is the following:

Row nr. 1 --> Title (Text, Ignored)
Row nr. 2 --> DeltaT (ms)
Row nr. 3 --> Number of Data = N
Row nr. 4 --> Data nr.1
Row nr. 5 --> Data nr.2
Row nr. 6 --> ..
Last Row ---> Data nr.N

Example (4096 data, Fs=48kHz):

My Impulse Response
0.0208333 <-- This is DeltaT (ms); DeltaT=1000/Sampling Freq.
4096 <-- This is the number of the following Data
0.00114076 <-- This is the Data nr. 1
0.00135692 <-- This is the Data nr. 2
...

The above format is very similar to files exported by MLSSA system. IR and Scope Data are exported by Sample Champion in this format when the Simple Form option is enabled.

Clear selected data


(1) With this option IR Data between "Selection A" cursors can be set to zero.

Overlay generated signal



(1)
With this option, the WAVE generated by the internal signal generator can be overlaid with the sampled data (in Scope Mode). This can be extremely useful for comparing the result of a measurement with the Ideal wave in the Time Domain. In the above example is shown a 200 Hz Square wave (the sampled wave is green and the generated wave is fuchsia).


Audio Device Selection

In Settings/Hardware Window the Audio Device used by Sample Champion can be selected (if more than one are installed in the PC). When a device is selected, the internal mixer will be updated (for the selected device) next time Sample Champion is run.
