It is the only free software system I could find -focusing on measuring speakers and audio frequency response. In the -process I also found an interesting article from NOVO on -<a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding -Speaker Specifications and Frequency Response</a> and an article from -ecoustics on -<a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding -Speaker Frequency Response</a>, with a lot of information on what to -look for and how to interpret the graphs. Armed with this knowledge, -I set out to measure the state of my speakers.</p> - -<p>The first hurdle was that AUDMES hadn't seen a commit for 10 years -and did not build with current compilers and libraries. I got in -touch with its author, who no longer was spending time on the program -but gave me write access to the subversion repository on Sourceforge. -The end result is that now the code build on Linux and is capable of -saving and loading the collected frequency response data in CSV -format.

I can not hear several of these are high -frequencies, according to measurement from -<a href="http://freehearingtestsoftware.com">Free Hearing Test -Software</a>, an freeware system to measure your hearing (still -looking for a free software alternative), so I do not know if they are -coming out out the speakers.

This setup was able to see the high frequency tones, so -the problem with my stereo had to be in the amplifier or speakers.</p> - -<p>Anyway, to try to role out one factor I ended up picking up a new -set of speakers at a flee marked, and these work a lot better than the -old speakers, so I guess the microphone and amplifier is OK.

It is time to repeat the calculation using updated +numbers. The calculation is based on how much data storage is needed +for each minute of audio, how many minutes all the calls in Norway +sums up to, multiplied by the cost of data storage.</p> + +<p>The number of phone call minutes for 2018 was fetched from +<a href="https://ekomstatistikken.nkom.no/">the NKOM statistics +site</a>, and for 2018, land line calls are listed as 434 238 000 +minutes, while mobile phone calls are listed with 7 542 006 000 +minutes. The total number of minutes is thus 7 976 244 000. For +simplicity, I decided to ignore any advantages in audio compression the +last four years, and continue to assume 60 Kbytes/min as the last +time.</p> + +<p>Storage prices still varies a lot, but as last time, I decide to +take a reasonable big and cheap hard drive, and double its price to +include the surrounding costs into account.
