What, you think that I left the speakers running so that the microphone could record them? Or did you think that the sound of Thursday evening traffic in St John's Wood would carry across six timezones? Or you think that's it's impossible that I should have been able to record sound the computer is playing (from whatever source, external or internal) on an OOTB PC for over twenty years? Is that why you're shouting? Anyway, back to talking about PCs. > To achieve it requires either a hardware connection > between the output and the input of the sound controller That's my understanding. Using the terminology of the High Definition Audio Specification (Revision 1.0a June 17, 2010), there is presumably a link from the § 7.2.3.4 Mixer (Summing Amp) Widget output to the § 7.2.3.5 Selector (Multiplexer) Widget. This link in inside the Widget Interconnection "Cloud" of Figure 49, Module-Based Codec Architecture. "The exact number of possible inputs to each widget is determined by design;" (§ 7.1.1), which is why you can't just conjure up any facility on any PC. But the machine is no more "specifically" configured than any PC which has HDA and a mobo: the vendor (Intel on my old one, Dell on the new) decides how much of the architecture they will implement. And the modern way seems to be to go cheap, particularly with consumer-grade. OK, this one's a decent machine, but it's still a 10-yr old cast off. Perhaps take a look at the specification and see how much is left open to the vendor. Hence the need for scripts like alsa-info to tell you exactly what you've bought with any given "sound card". This PC was not cheap when it was bought, largely because it's supposed to be fast: it was bought for students to run geophysics programs on. You can now pick them up for just over $100. If I ever have to hand it back, I might just do that. It'll be the first computer I've ever bought. > or the > collaboration of the sound driver. I assume by this that you're talking about pulseaudio. That's why I've mentioned it each and every time. (This is the third—should I put it in my signature?) I can't advise how the OP might use it, because *I* don't¹. But perhaps that's not expected here—one just replies "pulseaudio" like the people saying "audacity" or "sox" or whatever. Finally, who's the audio expert round here? I posted what I think is a determining factor for just vanilla ALSA and the card to work with my command line. Presumably there's a definitive answer to this? Do *you* have it? ¹ self-imposed simplicity: no PA, no OSS. Cheers, David.

No need of playing with cable loops. another possibility: when the snd-mixer-oss module is loaded, (at least here) when using the OSS mixer device there is a "Vol" control which roughly appears to be the OSS equivalent to Alsa's "Master" control, however the "Vol" control has an additional "Capture" switch. Now, when I set "Vol" as capture device, the audio output will be used as input for recording. Recording level can be adjusted with the "PCM" mixer control. Of course, the presence of this "Vol" control may depend on the sound card / driver in use. Oddly, there seems to be no such easy way to achieve the same result with alsamixer/amixer.

That's why I wrote "If you can't get ALSA to work…". You're a candidate for pulseaudio, I assume. Not sure about that command above (no means to try it just now), but _with_ PulseAudio, I can record the sound that is being played back just fine by means of "monitor" audio devices. E.g. I have the following command to record my screen (`0:v`), the "monitor" device (`1:a`) and a microphone (`2:a`): exec ffmpeg -video_size 1600x1200 -framerate 12 -f x11grab -i :0.0+0,0 -f pulse -ac 2 -i 0 -f pulse -i 1 -c:v libvpx-vp9 -deadline realtime -b:v 2M -c:a libvorbis -map 0:v -map 1:a -map 2:a "recording.webm" adapted from these two sources: -> https://trac.ffmpeg.org/wiki/Capture/Desktop -> https://askubuntu.com/questions/682144/capturing-only-desktop-audio-with-ffmpeg It may of course be true that the hardware _does_ support/accellerate this monitoring capability, but it does not seem to be entirely uncommon a feature? Here, it even works inside virtual machines :) Btw. the existence of monitor devices can be checked in `pavucontrol` where under "Output" it lists two monitor devices here: One for the HDMI output and one for the "Built-in Analog Stereo" Output. AFAICT, this recording facility is getting harder to find on most computers, if you're not prepared to fork out for a sound card. I've been fortunate, in that just as my ancient Pentium III expired, I have acquired a Dell Precision T3500 which has a well endowed (integrated) sound card. I'm still finding my way round it: for example, it also has HDMI playback, but I haven't yet worked out how to exploit it. The machine has one DVI output and two DisplayPorts, so I need to find a DisplayPort/HDMI adapter to see if that would yield anything. [...] As far as I can tell, DisplayPort can transport audio without the need for an HDMI adapter. Here, a Radeon Pro W5500 graphics card is connected to a Dell U2713HM display which has one HDMI, DP, VGA and DVI input each. The W5500 is connected to the DisplayPort and if I play sound to the "HDMI" output, the display outputs that sound through its headphones socket. Similar to your case, there are no HDMI ports on the graphics card. In my case, it is only DisplayPorts. HTH Linux-Fan öö pgpoa49bihnMC.pgp Description: PGP signature

The FFmpeg wiki has some very useful information on concatenating media files where a simple 'cat' won't work - I use its 'concat demuxer' regularly to contatenate MP4 files (Android starts a new video file when a 4GB limit is hit): https://trac.ffmpeg.org/wiki/Concatenate Celejar
Re: how to record sound to mp3
Greg Wooledge (12021-03-25): > I was told *by the developer* (Monty, in #vorbis IRC long ago) that > Ogg Vorbis files were designed for this. Yes, I know concatenation is supposed to be a feature, but they messed it up. You may not know, but the expert consensus is that, although the codec Vorbis was excellent, and Opus even better, the design of the format Ogg was terrible. The non-working concatenation is not the worse part. The worse part is probably that supporting any new codec in Ogg requires code, and non-trivial code even. Look at this: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=blob;f=libavformat/oggparseopus.c Compare to what it takes to support the same codec in Matroska: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=commit;h=30549294ef0f796d48b1ffa482bd9315d4dbb83c > However, I will note that there *are* players that don't handle > chained Ogg Vorbis files properly. So, make sure you test with the > actual player you intend to use. If concatenation really did work, it would work with all players, because they would not even be able to detect it happened. But it is worse than that, it is not weird players not handling the format correctly that do not work. Concatenation works with players that play it fast and loose with the format and fails with players that support it completely, because they take the serial id of the streams into account.

A few Google searches to provide supporting evidence: https://linux.die.net/man/1/oggz-merge If you want to create a file containing some Ogg files sequenced one after another, then you should simply concatenate them together using cat. In Ogg this is called "chaining". If you cat Ogg Vorbis I audio files together, then the result will also be a compliant Ogg Vorbis file. https://hydrogenaud.io/index.php?topic=114262.0 Chaining in an ogg container is as simple as it gets. Just concatenate two separate ogg files together, the result is a chained file. However, I will note that there *are* players that don't handle chained Ogg Vorbis files properly. So, make sure you test with the actual player you intend to use.

It's the other way around. Pure MP3 files are just a concatenation of self-delimited packets, concatenation will just work. MP3 files will usually have ID3 and/or XING packets for metadata at the beginning or the end, concatenation will include them, and the metadata will be invalid, but it will not prevent the file from being played. On the other hand, Ogg files are NOT concatenable, even those that contain only Vorbis audio. Some player will ignore the discontinuity at the concatenation points, but not all.

One way is to run alsamixer in an xterm. Help is in the top-right corner. $ arecord -l will give you a list of capture devices. To record, you could type, for example, in another xterm: $ arecord -d 10 -f cd -v -v -v -D plughw:0,0 /tmp/audiofile.wav where 10 gives you ten seconds; 0 gives you infinite (^C to stop), cd gives higher quality (44100) than the default, dat would give you the more modern 48000, -v … gives a crude VU meter, 0,0 is the bit you have to determine from arecord -l ⮤ device ⮤ card (usually 0, but matters if you have, say, PCH and HDMI).
