	OT: How to enable Mic Playback in windows by T o n g :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, On Linux, I can use my mic + laptop as a cheap and portable solution to amplify speech. I only need to turn on the Mic Playback with alsa and the laptop speaker will amplify sound from the mic without any other tools. I'm wondering if anyone know if it is possible to achieve the same under Windows. I'm trying to find a portable solution for an old lady who don't even know computer quite well.

Not answering your question . . . but you can get a mic pre-amp for less than 100 euro/dollar. Plug mic in, adjust volume (nice reassuring rotary/slide controls;-)> and plug in headpones or/_and_ a pair of computer speakers. Thomann.de (with which I have no connection) have a Behringer UB802 eight channel mixer for 52 euros (you could easily spend more on leads;-)>. I have seen two channel mic mixers somewhere, but thought 52 euros was not a bad starting price as a thought experiment. Michael PS Most mixers allow you to cut bass (c.50Hz) and have a 2/3 level equaliser, which might also help ... again without nasty GUI stuff! ------------------------------------------------------------------------------ Come build with us!

AUDACITY has Linux/Mac/M$ versions. in the 'Preferences' dialogue for the Linux version at least there is the option to 'play through' or some such (i.e. output is the same as recorded input, or not). If that is the case on M$, then it is doable, either with Audacity or by finding another tool that does the same.

Unfortunately, I don't think the currently released version of SoX can do this on Windows -- I get an error if I try to use the oss driver for both input and output at the same time. (You could probably pipe from one SoX to another, but that gets messy and increases latency.) The next version of SoX will have a new driver that works better on Windows, but it hasn't been released yet. If you want to try it, I made a prerelease build. You can download it here: http://cid-75d87767e802bc6e.skydrive.live.com/self.aspx/Public/SoX/SoX.14.3.1.prerelease.zip The SoX syntax to hook up the default input to the default output is: sox -d -d If there is too much delay between input and output, you can reduce it by using a smaller buffer: sox --buffer 1024 -d -d You can use the Windows Control Panel for Sound to pick which device (microphone, line in, etc.) is the default input. Alternatively, you can manually specify the input device by number. Devices are numbered starting at 0. To play from input device 0 (perhaps the microphone) to output device 0 (perhaps the speakers) you would do this: sox -t waveaudio 0 -t waveaudio 0 ------------------------------------------------------------------------------ Come build with us!

You can download it . . , thanks everyone for the reply. I'll try sox first, then Audacity if sox failed.
