Paso 1: Esta vez grabar de verdad

Apriete el botón rojo Grabar imagen del botón rojo de grabación en la barra de herramientas de control y luego empiece a hablar o tocar. Continúe cuanto desee. Cuando sienta que ha grabado suficiente, apriete el botón Detener imagen del botón amarillo de detención.

Intente aspirar a un pico máximo de alrededor de –6dB (vea: dB) o 0.5 si usted tiene los medidores ajustados a lineal en vez de dB.

Consejo: Alargar la barra de herramientas de medición al apretar y arrastrarla auida considerablemente en esta tarea.

Paso 2: Remover cualquier desplazamiento DC

Los desplazamientos DC pueden ocurrir en la etapa de grabación haciendo que la onda grabada no quede centrada en la línea horizontal en una amplitud de 0.0. Esto puede ser causado por una tarjeta de sonido con fallos. Si este es el caso con su grabación, use el efecto Normalizar para remover cualquier desplazamiento DC. Ponga una marca en "Eliminar cualquier desalineación DC..." pero deje "Normalizar amplitud máxima..." desmarcada.


Paso 3: Editar grabación

You now have a good recording, but there are likely some bits at the beginning and end that you don't need - between the time you clicked the Record button and the time you starting talking or playing, and between the time you stopped talking or playing and the time you clicked the Stop button.

  • Click the Skip to Start button Rewind.png in Transport Toolbar
  • Repeatedly click the Zoom In button Tool edit zoomin.png until the displayed waveform expands so you can see from the beginning of the recording to the time you started talking or playing
  • With the Selection tool, click just before the point where you started talking or playing
  • Choose Edit > Select > Track Start to Cursor
    • The region from the beginning of the track to the beginning of your performance is selected
  • Choose Edit > Remove Audio > Delete
    • The selected audio is removed from the track, and the rest of the audio moves left to fill the space left after the delete.

Similarly, you can delete the extra bit from the end of your recording.

  • Click the Skip to End button FFwd.png in Transport Toolbar
  • Repeatedly click the Zoom In button until the displayed waveform expands so you can see from the time you stopped talking or playing to the end of the recording
  • With the Selection tool, click just after the point where you stopped talking or playing
  • Choose Edit > Select > Cursor to Track End
    • The region from the end of your performance to the end of the track is selected
  • Choose Edit > Remove Audio > Delete
    • The selected audio is removed from the track

If you've made any mistakes in your performance you could edit them out. Use the Selection Tool to select each mistake and press the delete key. Listen back to each edit to make sure it sounds natural. If not, choose Edit > Undo Delete and try again.


Paso 4: Ajuste de amplitud

Since you were careful not to record too loud it is likely that your recording is not as loud as possible. To correct this you can use the Normalize effect.

  • Choose Edit > Select > All to select all of the track.
    • With default Tracks Preferences, you may not need this step - all the audio in the project is selected if you choose an effect without first selecting any audio.
  • Choose Effect > Normalize....
    • Accept (for now) the default choices in the Normalize dialog and click the OK button
    • The volume is normalized to -1 dB, so leaving a little headroom below the maximum possible 0 dB level.

Note that Normalize defaults to retaining the existing balance between stereo channels. However basic consumer-level equipment can often record with channels unbalanced. To correct unwanted volume differences between left and right, check "Normalize stereo channels independently".

Extraneous noises in the recording can cause Normalize to create unwanted changes in the stereo balance, or prevent recordings being made as loud as they can be. Extraneous noises should be edited with Click Removal, Repair or Amplify before the Normalize step. Also see our tips for reducing noise in the recording chain.

Paso 5: Guardar y exportar

Choose File > Save, choose a name for your project and a place to save it.

You have now saved an Audacity Project to disk. The project file (ending in .aup) can only be opened by Audacity. You can come back to the project and make changes to it later. For example you could do more editing, record more audio, or apply other effects.

To listen to your performance in other audio software (such as iTunes or Windows Media Player), or to burn it to CD, choose File > Export....
