The Raspberry Pi board doesnt have an audio input, but the Hifiberry compaible module does indeed have a audio input.
The HiFiBerry DAC+ ADC is a high-resolution digital-to-analog and analog-to-digital converter for the Raspberry Pi. This is a special sound card for the Raspberry Pi, optimized for one specific use case: the best audio playback quality. It is specifically designed for applications that do not only need playback, but also recording functionalities. See a detailed description for the use of dynamic microphones in combination with your DAC+ ADC over here.
Facts
Stereo input and output
Dedicated 192kHz/24bit high-quality Burr-Brown DAC
Dedicated 192kHz/24bit high-quality Burr-Brown ADC
Hardware volume control for DAC. You can control the output volume using “alsamixer” or any application that supports ALSA mixer controls.
Connects directly to the Raspberry Pi, no additional cables needed
Balanced input supported with optional XLR-connectors
No soldering, comes as a pre-fabricated kit. You just plug it onto the Raspberry Pi, it is conform to the Raspberry Pi hardware-attached-on-top (HAT) specification.
Compatible with all Raspberry Pi models with a 40-pin GPIO connector
Directly powered from the Raspberry Pi, no additional power supply
Three ultra-low-noise linear voltage regulators for optimal audio performance
HAT compliant, EEPROM for automatic configuration
Gold plated RCA output connectors
Comes with all components required to mount it
Audio input requires updated Linux kernel
