==Πώς γίνεται στερεοφωνική ηχογράφηση;==
Audacity by default should already be set to record in stereo.  If this is not the case, use [[Device Toolbar]] to select the playback and recording devices and to set the channels to '''"2 (stereo) Recording Channels"'''.

Alternatively you can open the [[Preferences|Audacity Preferences]], choose the “[[Devices Preferences|Devices]]” section on the left, then in the "Recording" panel, change the number of recording channels to "2 (Stereo)".
<div class="note">
'''Windows 10, Windows 8, Windows 7 and Windows Vista:''' Many USB recording devices, even if stereo, are seen as "microphones" so set by Windows to record in mono. If Audacity is set to record in stereo this will cause both channels to have the same content as one of the channels. To set Windows to record the device in stereo:
<ol><li> By the system clock, right-click over the <span class="menu">Speaker icon > Recording Devices</span> then right-click over <span class="menu">USB Audio Codec > "Properties"</span>
<li> On the "Advanced" tab, in the "Default Format" section, make sure the dropdown menu is set to '''"2 channel 16-bit 44100 Hz"'''.</ol>

<div id="olevel"></div>

==Ποιο είναι το βέλτιστο επίπεδο ηχογράφησης;==
Using the Recording Volume Slider on [[Mixer Toolbar]] to adjust the level, aim for a maximum peak of around –6 '''''[[Glossary#decibel|dB]]''''' on the [[Meter Toolbar#recording|Recording Meter]] (or 0.5 if the meter is set to '''''[[Glossary#linear|linear]]''''' scale). This should ensure that '''''[[Glossary#clipping|clipping]]''''' will be avoided. The recording will only show a maximum peak of around 0.5 on the default [[Audacity Waveform|waveform]] display, but given how the ear hears sound, this is actually much louder than apparent "half volume". 

You can boost the level if necessary after recording and editing by using <span class="menu">Effect > [[Effect Menu#amplify|Amplify]]</span> or <span class="menu">Effect > [[Effect Menu#normalize|Normalize]]</span>.

#Set Audacity to [[#How can I record in stereo?|record in stereo]].
#Plug one end of a stereo cable into the "Line Out" or "Headphone" connector on your tape deck, MiniDisc player, or stereo system. Plug the other end into your computer’s "Line In" port. If you do not have a suitable cable, you can find one at an electronics store.
#Choose "Line In" as the recording source in Audacity's [[Device Toolbar]] or [[Devices Preferences]]. 
#Press the red '''Record''' button. While Audacity is recording, start playing your tape or disc. When you have captured the audio you want to record, press the yellow '''Stop''' button. You can also press the blue '''Pause''' button to pause recording, and Pause again to resume recording on the same track.

For a detailed tutorial, see [[Tutorial - Copying tapes, LPs or minidiscs to CD|Copying tapes, LPs or MiniDiscs to CD]]. This covers all the steps from recording your records, cassettes or MiniDiscs to exporting as an audio file and burning to an [[Burning music files to a CD|audio CD]]. 

Vinyl or shellac records can also be recorded into Audacity with a special type of turntable that connects to the USB port of your computer. These turntables need to be set up differently from those that connect to line-in. See [[Recording with USB turntables|Recording with USB turntables or USB cassette decks]] for setup instructions, then [[Basic Recording, Editing and Exporting]] in the main tutorial. 

<div class = "note">
'''Connection hints:'''
* '''Do not connect a turntable directly to your computer.''' The signal from a turntable must be passed through a phono pre-amplifier or a receiver with a “phono” input that provides phono amplification. Otherwise, it will be too quiet and will also sound "tinny" due to incorrect equalization.  

* '''Do not plug stereo equipment into your computer’s “Microphone” port.''' This port is usually designed only for low level, mono microphone input. It will produce distortion if you connect phono amplified output. Use the “Line In” port if you have one (on some laptops or other portable computers, the "Mic" port can be switched to a line-level input). See [[How to connect your equipment#avoid_mic|further help]].

<div id="overdub"></div>

==Μπορεί να αναπαράγεται ένα κομμάτι, ενώ ηχογραφείται ένα άλλο κομμάτι από πάνω του;==
This is known as recording an '''''overdub''''' to create a '''''multi-track''''' recording. It makes it possible to record harmonies with yourself, or add new instruments or vocals to an existing recording. To do this in Audacity, follow these instructions:

#Select the recording device you are plugged into (probably microphone or line-in) in the Recording Device menu in [[Device Toolbar]] 
#* If you do not see your required recording device, enable it and make it default in the [http://wiki.audacityteam.org/wiki/Mixer_Toolbar_Issues#Further_help operating system's mixer], then in Audacity, choose <span class="menu">Transport > Rescan Audio Devices</span>     
#[[Importing Audio|Import]] or record the first track 
#Choose <span class="menu">Transport > Overdub (on/off)</span> 
#Press the '''Record''' button [[Image:Record.png|link=|Record button image]]&nbsp;.
<div class="note">If you are recording from a microphone, make sure you use headphones so that the microphone picks up only what you are recording. Detailed, illustrated instructions on how to make overdub recordings are in [[Tutorial - Recording Multi-track Overdubs]]. </div>

<div id="streaming"></div>

==Μπορεί το Audacity να ηχογραφήσει από YouTube, διαδικτυακό ραδιόφωνο ή άλλη ροή ήχου;==
*With most Windows and Linux audio devices, it is possible to record whatever sound the computer is currently playing, including internet radio streams.
*Mac users can capture streaming audio using third-party standalone applications or system extensions. 
See the [[Tutorial - Recording audio playing on the computer|Recording audio playing on the computer]] tutorial for details, following the link thereon for your particular operating platform.

<div id="remaining"></div>

== Ποια είναι η μέγιστη διάρκεια ηχογράφησης; ==
Audacity does not restrict the maximum recording length beyond the practical limitation that recording takes space on your drive so you can only record while the drive still has space available. 

When you start to record, Audacity shows a "Disk space remains for recording" message in the [[Status Bar]] at bottom left of the Audacity window giving the current recording time available. With default Audacity settings, stereo recording takes 1.2 GB of space per hour. 
{{note|After recording you will still need space to [[File Export Dialog|export]] the recording as an audio file for your computer. Editing the recording before export takes extra space. Each edit of a region requires as much extra disk space as was required to originally record that section.}}

To get more recording time:
* Delete your old files and folders (especially your old [[Audacity Projects|Audacity Project]] files and _data folders when you have finished with them)
* Select an alternative drive that has more space in the [[Directories Preferences]] (but do not record to an external USB or Firewire disk because recording needs disk access to be as fast as possible)
* Record in mono instead of stereo (settable at "Recording Channels" in [[Device Toolbar]] or in [[Devices Preferences]])
* Set the "Default Sample Format" in [[Quality Preferences]] to 16-bit instead of 32-bit (this is a good choice for a "quick recording" which you export at once without editing).

See [[Recording length]] for more details.

<div id="timer"></div>

==Μπορεί να ρυθμιστεί το Audacity να ηχογραφήσει κάποια συγκεκριμένη ώρα;==

Yes! See [[Timer Record]] in the [[Transport Menu|Transport menu]].

You can also make Audacity stop recording after a certain time limit without using the Timer Record feature, by following these steps:

#Turn on "Overdub: Play other tracks while recording new one" in the "Recording" section of the preferences (you can also turn Overdub on or off in Transport Menu)  
#Choose "Add New > Mono Track" from the Tracks menu (even if you will record in stereo).
#Zoom out if necessary, then click and drag to select the amount of time you want to record. 
#Start recording. Audacity will stop recording automatically when it reaches the end of the selected area.

<div id="multi"></div>

==Μπορεί να γίνει ηχογράφηση από πολυκάναλη συσκευή (περισσότερο από στερεοφωνικό);==
Yes, but this is not simple; typically this does not work "out of the box" on Windows consumer systems, and always requires use of appropriate hardware and device drivers. There are some known Audacity limitations in channel selection and channel-to-track allocation. It is essential that sample rates are matched in all places (Audacity, the operating system and the device).   
See [http://wiki.audacityteam.org/wiki/Multichannel_Recording this Wiki article] for more details.

<div id="twomics"></div>
==Γίνεται ταυτόχρονη ηχογράφηση από δύο μικρόφωνα (ή ακόμα από δύο κάρτες ήχου);== 
Audacity can only record from one sound device at a time, but here are some solutions.  
<ul>
<li> If your sound device has separate left and right mic inputs, connect the separate microphones to those inputs.
<li>Connect the separate microphones to a mixer and record from the mixer. 
<li> If these are dynamic microphones that do not need extra power, buy an adaptor that has two inputs for the microphones with a single 1/8 inch TRS connector for the computer microphone port (this will usually only give you a combined mono input).  
<li> Record each track to different computers.
<li> If you have two USB microphones or any other separate sound devices you can aggregate them as a single device for recording in Audacity, or use other recording software to record the two devices to separate tracks.
<ul><li>On '''Windows''' you can try the following.
<ul><li>Some applications can route two devices to one stream. Use [http://vb-audio.pagesperso-orange.fr/Voicemeeter/index.htm Voice Meeter] (donationware - see this [http://youtu.be/atobXq-iA-k YouTube video tutorial]) or [http://software.muzychenko.net/eng/vac.htm  Virtual Audio Cable] (not free).
<li> It may also be possible on Windows 10, Windows 8, Windows 7 and Windows Vista to use the "Listen" feature to route inputs to the output, though this is slightly lossy.
<ol><li>Right-click over the speaker icon by the system clock, then choose "Recording devices".
<li>Right-click over the first device, choose "Properties" then the "Listen" tab (if available). 
<li> Check "Listen to this device" and set it to play through the required soundcard. 
<li> Repeat the steps for the other devices. 
<li> Use the "stereo mix" feature on your soundcard (if it has such a feature) to [[Tutorial - Recording Computer Playback on Windows|record the computer playback]].</ol>
<li> [http://sourceforge.net/projects/alis/ Alis] can capture simultaneous recordings from different soundcards. 
<li>'''Advanced:''' Compiling Audacity with [http://wiki.audacityteam.org/wiki/ASIO_Audio_Interface ASIO] support will allow you to aggregate two USB microphones, for example using the [http://www.asio4all.com/ ASIO4ALL] driver for WDM Audio. Aggregating two devices that use ASIO drivers is unlikely to work correctly.</ul>
<li>On '''Mac OS X''' use Audio MIDI Setup to aggregate devices. See detailed instructions for  [https://support.apple.com/en-gb/HT202000 OS X 10.7 or later].
<li>On '''Linux''' you can use JACK to [http://jackaudio.org/faq/multiple_devices.html route two devices to one stream] that Audacity can record from. See also these two Forum posts<br>http://forum.audacityteam.org/viewtopic.php?f=27&t=56492&p=146769p142160#p142160<br>http://forum.audacityteam.org/viewtopic.php?f=27&t=56492&p=146769p142160#p146769 .</ul>
<div class="note">Separate audio devices such as two USB microphones or devices on different computers will have separate clock speeds (in the absence of a master clock to synchronize to). Therefore the two inputs may drift apart over time.</div>
