Hi,

Thanks for the great work.
This software doesn't seems to work with the latest saleae-logic-alpha 2.3.13-1.

There are two ways to export the data:

Time [s] | Channel 0 | Channel 1 | Channel 2
1.20147512 | 1 | 0 | 0
1.20147544 | 0 | 0 | 0
1.20147577 | 1 | 0 | 0
1.20147609 | 0 | 0 | 0
1.20147642 | 1 | 0 | 0

Or

name | type | start_time | duration | channel | data
I2S / PCM | data | 1.20148586 | 9.76E-06 | 0x0000000000000001 | 0x0000000000000000
I2S / PCM | data | 1.20149628 | 9.76E-06 | 0x0000000000000000 | 0x0000000000000000
I2S / PCM | data | 1.20150669 | 9.77E-06 | 0x0000000000000001 | 0x0000000000000000
I2S / PCM | data | 1.20151711 | 9.76E-06 | 0x0000000000000000 | 0x0000000000000000
I2S / PCM | data | 1.20152753 | 9.76E-06 | 0x0000000000000001 | 0x0000000000000000
I2S / PCM | data | 1.20153794 | 9.77E-06 | 0x0000000000000000 | 0x0000000000000000
I2S / PCM | data | 1.20154836 | 9.76E-06 | 0x0000000000000001 | 0x0000000000000000

Neither of these two ways seems to generate a valid file.

I was unable to install PCM2Wav==1.3 on some installations, and I narrowed down the cause to the fact that only a .egg file is available in PyPI for 1.3: https://pypi.org/project/PCM2Wav/1.3/#files

Is it possible to add the .tar.gz file, similar to what is available for 1.2? Thanks!

I've noticed that when calling the PCM2Wav constructor, it is not taking the channel number specified in the CSV file into consideration. For example, if we have the following CSV sample:

0.000011560000000,2,0
0.000021960000000,1,6785
0.000032360000000,2,0
0.000042800000000,1,6906
0.000053200000000,2,0
0.000063640000000,1,5487

The generated WAV file will have a silent left channel (since it takes whatever is in the first row as left channel, despite being channel 2). If we remove the first line, the generated WAV file will now have a silent right channel (i.e. swapped channels). Do you think this is something that this module should automatically handle?

I'd like to convert Saleae logicpro pcm file to wav,
But it shows some issue.

1. UnboundLocalError 'channels'

File "D:\python_project\pcm2wav2\PCM2Wav\PCM2Wav.py", line 54, in _generate
frame = self._calc_frame(channels)
UnboundLocalError: local variable 'channels' referenced before assignment

2. short variable format issue.

Source code only support 'short' variable format:(-32768) <= supported value <= 32767
So, it makes error when value is out of range.
Some value was 65532,......
Can I modify "__formats = {1: 'c', 2: 'h'}" --> __formats = {1: 'c', 2: 'i'}?

3. Can somebody share good example of csv file working with this source code?

• I attached what I used csv file.

i2s.zip

I did capture I2S audio data using Saleae Logic Pro.

(using 1.2.18)

Options menu → Export data → Export (i2s.csv *download here)

and use python commands, export wav.file. (example.wav *download here)

but it's wrong file.
Please help me.
