# Clarifications
## Is WinXP supported?
No WinXP SP2 based "Chrome" support. However, RecordRTC works on WinXP Service Pack 3.
## Is Chrome on Android supported?
RecordRTC uses WebAudio API for stereo-audio recording. AFAIK, WebAudio is not supported on android chrome releases, yet.
Firefox merely supports audio-recording on Android devices.
## Stereo or Mono?
Audio recording fails for `mono` audio. So, try `stereo` audio only.
MediaRecorder API (in Firefox) seems using mono-audio-recording instead.
## Possible issues/failures:
**This section applies only to StereoAudioRecorder:**
Do you know "RecordRTC" fails recording audio because following conditions fails:
1. Sample rate and channel configuration must be the same for input and output sides on Windows i.e. audio input/output devices mismatch
2. Only the Default microphone device can be used for capturing.
3. The requesting scheme is none of the following: http, https, chrome, extension's, or file (only works with `--allow-file-access-from-files`)
4. The browser cannot create/initialize the metadata database for the API under the profile directory
If you see this error message: `Uncaught Error: SecurityError: DOM Exception 18`; it means that you're using `HTTP`; whilst your webpage is loading worker file (i.e. `audio-recorder.js`) from `HTTPS`. Both files's (i.e. `RecordRTC.js` and `audio-recorder.js`) scheme MUST be same!
## Web Audio APIs requirements
1. If you're on Windows, you have to be running WinXP SP3, Windows Vista or better (will not work on Windows XP SP2 or earlier).
2. On Windows, audio input hardware must be set to the same sample rate as audio output hardware.
3. On Mac and Windows, the audio input device must be at least stereo (i.e. a mono/single-channel USB microphone WILL NOT work).
## Why stereo?
If you explorer chromium code; you'll see that some APIs can only be successfully called for `WAV` files with `stereo` audio.
Stereo audio is only supported for WAV files.
RecordRTC is unable to record "mono" audio on chrome; however it seems that we can covert channels from "stereo" to "mono" using WebAudio API, though. MediaRecorder API's encoder only support 48k/16k mono audio channel (on Firefox Nightly).
