menu "microFLAC Decoder"

    choice MICRO_FLAC_MEMORY_PREFERENCE
        prompt "Memory allocation preference"
        default MICRO_FLAC_PREFER_PSRAM if SPIRAM
        default MICRO_FLAC_INTERNAL_ONLY
        help
            Choose memory allocation preference for FLAC decoder buffers.

            The decoder allocates a working buffer based on max_block_size
            from STREAMINFO (typically 16-64KB for stereo). This setting
            controls where that buffer is allocated.

        config MICRO_FLAC_PREFER_PSRAM
            bool "Prefer PSRAM, fall back to internal RAM"
            depends on SPIRAM
            help
                Try to allocate from PSRAM first. If unavailable, fall back
                to internal RAM. Recommended for most use cases.

        config MICRO_FLAC_PREFER_INTERNAL
            bool "Prefer internal RAM, fall back to PSRAM"
            depends on SPIRAM
            help
                Try to allocate from internal RAM first. Better performance
                but uses precious internal RAM.

        config MICRO_FLAC_PSRAM_ONLY
            bool "PSRAM only (fail if unavailable)"
            depends on SPIRAM
            help
                Only allocate from PSRAM. Allocation will fail if PSRAM is
                not available. Use when internal RAM must be reserved for
                other components.

        config MICRO_FLAC_INTERNAL_ONLY
            bool "Internal RAM only"
            help
                Only allocate from internal RAM. Ignores PSRAM even if
                available. Best performance but highest internal RAM usage.

    config MICRO_FLAC_ENABLE_XTENSA_ASM
        bool "Enable Xtensa assembly optimizations"
        default y if IDF_TARGET_ESP32 || IDF_TARGET_ESP32S3
        default n
        help
            Enable Xtensa assembly optimizations for LPC prediction
            restoration.

            Uses MULL/MULSH and hardware loop instructions on ESP32 and
            ESP32-S3 for significantly faster decoding. Only available
            on Xtensa-based targets.

    config MICRO_FLAC_ENABLE_OGG
        bool "Enable Ogg FLAC container support"
        default y
        help
            Enable support for Ogg FLAC container format (.oga/.ogg files).

            When disabled, only native FLAC files are supported, saving
            approximately 3-5 KB of flash and eliminating the OggDemuxer
            heap allocation. Disable this if you only need native FLAC
            decoding.
