  32         <p>While visiting a convention during Easter, it occurred to me that
  33 it would be great if I could have a digital Dictaphone with
  34 transcribing capabilities, providing me with texts to cut-n-paste into
  35 stuff I need to write.  The background is that long drives often bring
  36 up the urge to write on texts I am working on, which of course is out
  37 of the question while driving.  With the release of
  38 <a href="https://github.com/openai/whisper/">OpenAI Whisper</a>, this
  39 seem to be within reach with Free Software, so I decided to give it a
  40 go.  OpenAI Whisper is a Linux based neural network system to read in
  41 audio files and provide text representation of the speech in that
  42 audio recording.  It handle multiple languages and according to its
  43 creators even can translate into a different language than the spoken
  44 one.  I have not tested the latter feature.  It can either use the CPU
  45 or a GPU with CUDA support.  As far as I can tell, CUDA in practice
  46 limit that feature to NVidia graphics cards.  I have few of those, as
  47 they do not work great with free software drivers, and have not tested
  48 the GPU option.  While looking into the matter, I did discover some
  49 work to provide CUDA support on non-NVidia GPUs, and some work with
  50 the library used by Whisper to port it to other GPUs, but have not
  51 spent much time looking into GPU support yet.  I've so far used an old
  52 X220 laptop as my test machine, and only transcribed using its
  53 CPU.</p>
  54
  55 <p>As it from a privacy standpoint is unthinkable to use computers
  56 under control of someone else (aka a "cloud" service) to transcribe
  57 ones thoughts and personal notes, I want to run the transcribing
  58 system locally on my own computers.  The only sensible approach to me
  59 is to make the effort I put into this available for any Linux user and
  60 to upload the needed packages into Debian.  Looking at Debian Bookworm, I
  61 discovered that only three packages were missing,
  62 <a href="https://bugs.debian.org/1034307">tiktoken</a>,
  63 <a href="https://bugs.debian.org/1034144">triton</a>, and
  64 <a href="https://bugs.debian.org/1034091">openai-whisper</a>.  For a while
  65 I also believed
  66 <a href="https://bugs.debian.org/1034286">ffmpeg-python</a> was
  67 needed, but as its
  68 <a href="https://github.com/kkroening/ffmpeg-python/issues/760">upstream
  69 seem to have vanished</a> I found it safer
  70 <a href="https://github.com/openai/whisper/pull/1242">to rewrite
  71 whisper</a> to stop depending on in than to introduce ffmpeg-python
  72 into Debian.  I decided to place these packages under the umbrella of
  73 <a href="https://salsa.debian.org/deeplearning-team">the Debian Deep
  74 Learning Team</a>, which seem like the best team to look after such
  75 packages.  Discussing the topic within the group also made me aware
  76 that the triton package was already a future dependency of newer
  77 versions of the torch package being planned, and would be needed after
  78 Bookworm is released.</p>
  79
  80 <p>All required code packages have been now waiting in
  81 <a href="https://ftp-master.debian.org/new.html">the Debian NEW
  82 queue</a> since Wednesday, heading for Debian Experimental until
  83 Bookworm is released.  An unsolved issue is how to handle the neural
  84 network models used by Whisper.  The default behaviour of Whisper is
  85 to require Internet connectivity and download the model requested to
  86 <tt>~/.cache/whisper/</tt> on first invocation.  This obviously would
  87 fail <a href="https://people.debian.org/~bap/dfsg-faq.html">the
  88 deserted island test of free software</a> as the Debian packages would
  89 be unusable for someone stranded with only the Debian archive and solar
  90 powered computer on a deserted island.</p>
  91
  92 <p>Because of this, I would love to include the models in the Debian
  93 mirror system.  This is problematic, as the models are very large
  94 files, which would put a heavy strain on the Debian mirror
  95 infrastructure around the globe.  The strain would be even higher if
  96 the models change often, which luckily as far as I can tell they do
  97 not.  The small model, which according to its creator is most useful
  98 for English and in my experience is not doing a great job there
  99 either, is 462 MiB (deb is 414 MiB).  The medium model, which to me
 100 seem to handle English speech fairly well is 1.5 GiB (deb is 1.3 GiB)
 101 and the large model is 2.9 GiB (deb is 2.6 GiB).  I would assume
 102 everyone with enough resources would prefer to use the large model for
 103 highest quality.  I believe the models themselves would have to go
 104 into the non-free part of the Debian archive, as they are not really
 105 including any useful source code for updating the models.  The
 106 "source", aka the model training set, according to the creators
 107 consist of "680,000 hours of multilingual and multitask supervised
 108 data collected from the web", which to me reads material with both
 109 unknown copyright terms, unavailable to the general public.  In other
 110 words, the source is not available according to the Debian Free
 111 Software Guidelines and the model should be considered non-free.</p>
 112
 113 <p>I asked the Debian FTP masters for advice regarding uploading a
 114 model package on their IRC channel, and based on the feedback there it
 115 is still unclear to me if such package would be accepted into the
 116 archive.  In any case I wrote build rules for a
 117 <a href="https://salsa.debian.org/deeplearning-team/openai-whisper-model">OpenAI
 118 Whisper model package</a> and
 119 <a href="https://github.com/openai/whisper/pull/1257">modified the
 120 Whisper code base</a> to prefer shared files under <tt>/usr/</tt> and
 121 <tt>/var/</tt> over user specific files in <tt>~/.cache/whisper/</tt>
 122 to be able to use these model packages, to prepare for such
 123 possibility.  One solution might be to include only one of the models
 124 (small or medium, I guess) in the Debian archive, and ask people to
 125 download the others from the Internet.  Not quite sure what to do
 126 here, and advice is most welcome (use the debian-ai mailing list).</p>
 127
 128 <p>To make it easier to test the new packages while I wait for them to
 129 clear the NEW queue, I created an APT source targeting bookworm.  I
 130 selected Bookworm instead of Bullseye, even though I know the latter
 131 would reach more users, is that some of the required dependencies are
 132 missing from Bullseye and I during this phase of testing did not want
 133 to backport a lot of packages just to get up and running.</p>
 134
 135 <p>Here is a recipe to run as user root if you want to test OpenAI
 136 Whisper using Debian packages on your Debian Bookworm installation,
 137 first adding the APT repository GPG key to the list of trusted keys,
 138 then setting up the APT repository and finally installing the packages
 139 and one of the models:</p>
 140
 141 <p><pre>
 142 curl https://geekbay.nuug.no/~pere/openai-whisper/D78F5C4796F353D211B119E28200D9B589641240.asc \
 143   -o /etc/apt/trusted.gpg.d/pere-whisper.asc
 144 mkdir -p /etc/apt/sources.list.d
 145 cat > /etc/apt/sources.list.d/pere-whisper.list &lt;&lt;EOF
 146 deb https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 147 deb-src https://geekbay.nuug.no/~pere/openai-whisper/ bookworm main
 148 EOF
 149 apt update
 150 apt install openai-whisper
 151 </pre></p>
 152
 153 <p>The package work for me, but have not yet been tested on any other
 154 computer than my own.  With it, I have been able to (badly) transcribe
 155 a 2 minute 40 second Norwegian audio clip to test using the small
 156 model.  This took 11 minutes and around 2.2 GiB of RAM.  Transcribing
 157 the same file with the medium model gave a accurate text in 77 minutes
 158 using around 5.2 GiB of RAM.  My test machine had too little memory to
 159 test the large model, which I believe require 11 GiB of RAM.  In
 160 short, this now work for me using Debian packages, and I hope it will
 161 for you and everyone else once the packages enter Debian.</p>
 162
 163 <p>Now I can start on the audio recording part of this project.</p>

 187       <div class="body">
 188         <p>Today I finally found time to track down a useful radio frequency
 189 scanner for my software defined radio.  Just for fun I tried to locate
 190 the radios used in the areas, and a good start would be to scan all
 191 the frequencies to see what is in use.  I've tried to find a useful
 192 program earlier, but ran out of time before I managed to find a useful
 193 tool.  This time I was more successful, and after a few false leads I
 194 found a description of
 195 <a href="https://www.kali.org/tools/rtlsdr-scanner/">rtlsdr-scanner
 196 over at the Kali site</a>, and was able to track down
 197 <a href="https://gitlab.com/kalilinux/packages/rtlsdr-scanner.git">the
 198 Kali package git repository</a> to build a deb package for the
 199 scanner.  Sadly the package is missing from the Debian project itself,
 200 at least in Debian Bullseye.  Two runtime dependencies,
 201 <a href="https://gitlab.com/kalilinux/packages/python-visvis.git">python-visvis</a>
 202 and
 203 <a href="https://gitlab.com/kalilinux/packages/python-rtlsdr.git">python-rtlsdr</a>
 204 had to be built and installed separately.  Luckily '<tt>gbp
 205 buildpackage</tt>' handled them just fine and no further packages had
 206 to be manually built.  The end result worked out of the box after
 207 installation.</p>
 208
 209 <p>My initial scans for FM channels worked just fine, so I knew the
 210 scanner was functioning.  But when I tried to scan every frequency
 211 from 100 to 1000 MHz, the program stopped unexpectedly near the
 212 completion.  After some debugging I discovered USB software radio I
 213 used rejected frequencies above 948 MHz, triggering a unreported
 214 exception breaking the scan.  Changing the scan to end at 957 worked
 215 better.  I similarly found the lower limit to be around 15, and ended
 216 up with the following full scan:</p>

 218 <p><a href="http://www.hungry.com/~pere/blog/images/2023-04-07-radio-freq-scanning.png"><img src="http://www.hungry.com/~pere/blog/images/2023-04-07-radio-freq-scanning.png" width="100%"></a></p>
 219
 220 <p>Saving the scan did not work, but exporting it as a CSV file worked
 221 just fine.  I ended up with around 477k CVS lines with dB level for
 222 the given frequency.</p>
 223
 224 <p>The save failure seem to be a missing UTF-8 encoding issue in the
 225 python code.  Will see if I can find time to send a patch
 226 <a href="https://github.com/CdeMills/RTLSDR-Scanner/">upstream</a>
 227 later to fix this exception:</p>
